North/south isn't really the issue. It's the climate. Atlanta and San Diego are at latitudes similar to Arlington. Atlanta isn't as hot as Dallas, and San Diego is generally quite comfortable. Of course, the Marlins will have a retractable roof in the near future. Attendance in Texas hasn't been earth-shattering (about 27,000 per game over the past five years), but it's hardly a negative, either. As far as climate, having all games at night during the summer months seems to address that. From purely a fan standpoint, I don't think anything noticeable will happen. There'll be a Rangers team in Arlington now, and there'll be a Rangers team in Arlington in the future. From a business standpoint, however, it'll be interesting to see how this all plays out.
