Well, I'm the only one who hasn't made an introductory post yet, and the peer pressure is getting to me, so, I'm in Chicago but, coincidentally, born in Gainesville, FL and raised in even more uninteresting Ocala, FL. Actually my first TMBG concert was at the Reitz Union at the University of Florida, in 1990. It cost $5. Now I'm feeling nostalgiac.
The farthest I've traveled has been from Chicago to Harrisburg, PA, but I was in the Poconos anyway vacationing with the in-laws so I guess that doesn't really count. The farthest I've traveled specifically for TMBG was Chicago to St Louis. I've seen TMBG in 5 states (FL, IL, MO, IN, PA) and plan to add four more this summer: OH (Columbus), MI, WI and MN, the last two with artmonkeygirl
as she already mentioned. And, having conquered the Midwest, perhaps I'll move on to the South or Northeast at some point.
(By the way, I have mementos (scans, pictures, mp3s) from a lot of the shows I've been to on my website
