Qouting from my confirmation letter:

Here are some things you should bring:

Bedding, pillows, towels, flashlights (We have not seen the new site at
night, so we don't know how dark it is.), clothing for a variety of
weather (including warm, cool, cold, and wet or dry), musical
instruments, and voices. In addition, if you are coming Friday evening
please bring food for a potluck dinner.

As in previous years we will have a silent auction to raise money for
the Lieberman/Olive Scholarship Fund. That means we need donations to be
auctioned off. This is a good opportunity to pass on your old recordings
and books (and other stuff) that you are no longer using to others who
would like them. All of your donations are tax deductible. And bring
money or a checkbook, because you'll want to buy stuff from the auction,
as well as other crafts and CDs.

Things you should leave at home:

The West River Center is alcohol free, so please don't bring any. Pets
are also off limits. You can also leave your cares at home and plan on a
relaxing though exciting weekend.
