Wouldn't that be because Houston has it's own ball club??? I mean we have the O's on the tube here but I wouldn't expect that to be a similar experience in TX
I'm thinking distance might be part of it as well. DC/Baltimore is about 40 miles. Dallas/Houston is about 240 miles.
Depends. I used to get Phillies and Pirates in PA, territories overlap, but maybe not in the team's home city.
Home city could definitely play a part in it as well.
