What kind of campground are you starting from? State park? Private? I'd arrange with them to ship the stuff there, instead.

How about a bike shop?

Have you asked Adventure Cycling if they an offer any assistance with your gear when it's in VT? Maybe they have a location you can ship to/from?

Sounds like a lot of fun, but a LOT of riding! wow.

Good luck, and please post your solution. I'm very curious.
