I'm from Mississippi and have lived in Texas since 1981. I'm married a girl from Waco 45 years ago. Rural areas and small town Texas reflect old time values. The guy from NYC or Boston will be made to feel welcome here. You can bring your handgun and be legal. In case you broke down on the road, having it will be comforting. Big cities are just that--big cities. You have to avoid certain areas.
When I visited NYC a few years back, I met many nice people. I try to be a nice person and have learned that nice folks attract other nice folks.
