UPDATE 3
The reserved tent spots are officially filled! I'll add a new list if necessary for standby. Of course, anybody could roomate with somebody else, or just call and make their own reservations if spots are still available.
ETA: 10 days away!! Check:
TIRES. If in doubt, replace or bring a replacement(s) and tools. Never fails, somebody who was sure they were fine ends up showing cord 150 miles into a 300 mile day. If you can already see wear bars, don't wait.
GEAR: Gear 1, camping: If in doubt, get more/ better than you think you need. If you end up soaked because you brought your Snoopy tent and Barbie sleeping bag, you have my sympathy, but you ain't sharing my tent.
Gear 2, riding: BARE MINIMUM: Helmet, jacket, gloves, boots over the ankle, jeans. In this case, less is NOT more. If you don't have this bare minimum kit, beg, borrow or steal till you do.
BIKE: Beyond tires, work out whatever gremlins are buggin you, or whatever impending catastrophic failures are foreseeable. Chain tension, lever play, etc. Don't make the group wait while you fiddle fuses for heated grips.
