one more thought, i was walking down a tunnel at downtown crossing on my way back from braintree and was behind an obese woman. it struck me as bizarre. why? i started looking around and found mostly proportionate people, some overweight, but the sheer amount of obesity that i came to accept as normal in texas doesnt seem to be around. is it the convenience of walking? the weather? my sampling? the culture? or do blatantly obese people just not venture out much up here?
