I know the concert's in August and it's in New England somewheres, but I'll have to get the rest of the details for you, and I'll do that shortly. It might be the 40th anniversary of Tanglewood, or something like that.
Jeff, the eating/traveling conundrum can be managed. One way is to take up a different regimen of eating a month or two before you plan to travel. Eat at different times of the day, preferably only when you are hungry. Also, eat something that takes a while to digest, such as a meat-based sandwich or a baked potato. Over a little time, you can train your stomach not to kick in with the hunger pangs at a particular time of day.
