Fast food restaurants and grocery stores test-market products all the time by slipping them onto the shelves. So often, in fact, that average consumers may not even notice when they've tried something impermanent. But hotel rooms are a different beast. Renovations are expensive, so they can't just remodel rooms and cross their fingers. And sometimes, ideas that looked good on the drawing board turn out to be hitchy in practice.

Most of the big brands conduct most of their experiments behind closed doors. According to an illuminating exposé from Portfolio.com, Starwood (Westin and W Hotels), Hyatt's Summerfield Suites, and Marriott all run mini-properties stashed in private locations such as warehouses and office basements. Loyal customers are quietly invited to give new rooms a whirl, although they're not usually allowed to stay overnight.

But Hilton operates a wing of an otherwise anonymous Los Angeles-area hotel specifically for the purpose of trying out new room ideas. Regular guests check in and out of the test rooms, conveniently located near Hilton's corporate offices. To ensure that only brand devotees are exposed to potentially disastrous experiments, its El Segundo Hilton Garden Inn property (which is the only one of the 260 HGI properties that Hilton directly owns and operates) assigns the prototype rooms only to people with Diamond frequent-stay status. That translates to folks who stay in Hiltons for about two months a year.

You might think all the stories left to tell in this genre are about quaint family farms in the mid-West being overrun by giant corporations, but the latest salvo comes from industrial Los Angeles.

Two years ago, a community garden was razed to make room for a warehouse for the clothing retailer Forever 21, and now community activists are looking at the still-empty tract of land and they want their plants back.

The Los Angeles Times says the story is complicated by political ties -- the company made hefty donations to the mayor, Antonio Villaraigosa, who had initially opposed the destruction of the garden, which is located in South Central. This being L.A., there are celebrities involved: Daryl Hannah, Joan Baez and Danny Glover are among those who protested the initial plans, and it was the subject of the short documentary South Central Farm: Oasis in a Concrete Desert.

Don't look for the bright shiny new KFC anytime soon in South Central. Today Los Angeles will vote on whether to ban new fast food restaurants from opening in a wide-swatch of low-income area of town for a year. The reason? Obesity has soared in those areas.

The proposal, put together by councilwoman Jan Perry, would place a one-year ban on any new fast food restaurants opening in a 32-mile radius. About 500,000 residents, largely lower income citizens, would be affected.

Perry has said the idea behind the proposed moratorium, which could be extended for up to two years, was to offer residents of her district healthier food choice. The L.A. Department of Public Health last year released a study showing that that 30% of children in South Central were considered obese, compared to 25% of children city-wide.

It's interesting to think about how cities compete for tourists. Apart from spending billions of dollars on advertising, fighting to host World's Fairs and the Olympics, and desperately organizing major events, almost every aspect of a city's infrastructure could be seen as part of a bid for the tourist buck. Police? Handy for keeping the tourists safe. Public transportation? Offers a cheap way for the tourists to get around. Sports teams? Keeps the tourists happy while they're here and gives them handy souvenirs to take home!

I thought about this recently when I read about the town of Zheleznovodsk, Russia. Home to the Mashuk-Akva Term spa, the town seems to have long been casting about for a sense of identity. On the one hand, it is noted for the healing powers of its mineral springs; then again, so are many other towns in the Caucasus Mountains region, where it is located. Not long ago, it hit on the idea of using the iconic enema, the delivery system for many of its healing mineral treatments, as a sign of its civic pride. The first step was posters that stated "Let's beat constipation and sloppiness with enemas!" The signs hung in the local spa and garnered a fair bit of attention.

Buoyed by the success of their enema poster campaign, the spa commissioned a sculpture. Costing $42,000, Mashuk-Akva's enema statue shows an 800-pound bronze bulb-style enema being carried by three Botticelli-esque angels. While the sculptor admits to a certain irony in her finished work, the director of the spa considers it to be an utterly non-ironic symbol of the region. It remains to be seen if Zheleznovodsk's new sculpture will become a cultural icon or will end up being a washout. Regardless, the next time I take a trip, I'm going to give a long, hard look at Russia, the land of the golden enema!

Bruce Watson is a freelance writer, blogger, and all-around cheapskate. The more he thinks about it, the more he's impressed with Zheleznovodsk. Come to think of it, maybe New York needs an enema!
