Amazing...Montgomery County, MD, where I live, is #18. There must be some pretty thin folks about, 'cause I see a bunch doing their best to raise the average!
In the last few years, there are many more seriously obese people using powered chairs to shop. Well....maybe that's because all these programs to SELL powered chairs have allowed more obese folks to go shopping.

I do find it interesting that 3 areas around Wash DC are on the list...Montomgery, Arlington & Alexandria. But not DC itself or Prince Georges county, which have majority black populations. Poverty, culture, lifestyle & genetics sure do color demographic studies and maps.
