Come down to mid-o....show up by 8:30 and make the riders meeting to get a feel of how a day goes. Tons of places to spectate and when you get tired of running around, come hang in the pits and bs with the riders.
leather 1 pc is the way to go. Keep an eye out for used suits, some are not that pretty, but as long as there are no holes, stitching is in good shape and the thing fits....thats all that really matters IMHO.
