well, I know you addressed this to the people that DO travel, but I shall have my input anyway
I don't travel for BJ or anybody else. To me driving an hour north to a show is a major hassle and I only do it for really important shows - such as audioslave and velvet revolver

I missed at least 8 shows this summer because I couldn't be arsed to go to shows that require me sitting in traffic for 1.5 hours.
Guess I am spoiled. There are still more shows than I can afford to within a half hour drive.....
