Are Minnesotans more withdrawn than Texans?
I'm not sure about "withdrawn," but I know that if you trespass on ranch land in Texas you're likely to discover that Texans are more heavily armed. Do not disregard this sign.
When I was at Texas A&M and we were shooting video on ranches, it was a considerable comfort to me that the state cars we used had a large A&M logo on the side. As the land-grant university in TX, using the university name opens a lot of doors anywhere in the rural areas of the state.
