Two days ago, 2005 Eclipse Award-winning sprinter Lost in the Fog was put to sleep due to cancer that could not be cured. Bloodhorse has a very nice write-up about this most magnificent champion race horse.

His trainer Greg Gilchrist is quoted as saying, "We accomplished what we wanted to do. It was all about giving him quality time. We did everything we could for him. He was happy and content right up to the end. He went quietly and easily."

Last month, veterinarian Don Smith diagnosed Lost in the Fog with spleen cancer and cancerous tumors in his abdomen. Last year, Lost in the Fog made seven cross-country trips and won eight stakes, including the King's Bishop. Lost in the Fog won 10 races in a row to begin his career and 11 of 14 starts while earning almost one-million dollars.

At the time of Lost in the Fog's cancer diagnosis, Gilchrist stated "What a warrior -- I've never had a horse that comes close to this one."

When Lost in the Fog passed on, Gilchrist said, "It was very emotional. I probably won't ever get over it. I always said when it got too bad, Lost in the Fog would let me know. I think he did yesterday. If he was a person, he would have said, 'It's time.' That's life and we have to deal with it. People come and go. I'll just see him on the other side."

That's what I am calling AOL's list of top ten green cities -- the top ten cancer prevention cities -- because when it comes to reducing environmental cancer risks and promoting a healthy lifestyle, a city that is known as a green city is also a cancer prevention city. AOL's criteria in choosing the top ten green cities they believe are creating a healthy and livable place for its residents are: clean air and clean water, renewable energy, reliable city buses, trams, streetcars and subways, a growing number of parks and greenbelts, and farmer’s markets.

Not to claim bragging rights, but my hometown of Portland, Oregon is on the list. Austin, Texas; Minneapolis, Minnesota; Boulder, Colorado; Burlington, Vermont; Madison, Wisconsin; San Francisco, California; Santa Monica, California; Chicago, Illinois and New York, New York made the list. New York City? Yes. According to AOL's reviewers, Central Park goes a long way in making New York City a green city. As does the fact that 80 percent of the residents use public transportation. New Yorkers use fossil fuels at the rate the U.S. did in the 1920s. To learn all the ways these cities made the green list, go read AOL's Top 10 Greenest Cities. Or as I like to think of it -- the top ten cities promoting a healthy lifestyle and maintaining clean livable areas resulting in the creation of a cancer prevention environment -- the top ten cancer prevention cities.
