“But getting back to my original question, how many different Walmart stores have you visited in the last 6 months?”

I'm not sure I get the gist of your question - are you asking me to make sure I have a statistically valid sample or you personally know of a Walmart that's the exception?

I think it is ridiculous for you to contend that a nation of 300 million people is obese based on your visits to a Walmart store.
