I did 6 Bonnaroos in total - 03, 04, 05, 06, 08, 09. The advice given above is excellent although I'd disagree with staying further from Centeroo. The further you are the more time you spend in the sun getting cooked walking to the venue, the less likely you are to head back once you're in for the night, the harder it is to catch a nap when you need one (and you will need one) etc etc. Water and shade are your best friends. Skip either of these and you'll be in the med tent or worse. Bring footwear that's comfortable and you don't mind getting ruined. Bring a spare set of car keys in case you lose your only set (happened to me - not my fault - miraculous ending to the story) Don't expect to get in the front row for your favourite band. Rain gear is a must. If you're a poster collector bring a big empty tube and a big empty credit card. There's a waterfall near Manchester that's pretty cool. Jack Daniels distillery is a quick drive but it's in a dry county. I think you can drink at Maker's Mark on the way home... Nashville is fun. House Of Cash is terrible (although haven't tried to go there since 03 so could be drastically different.) Kentucky is fun. Cincinnati is fun.
