The Camp Oakes personnel have requested that NO pets will be allowed in the camp unless it is a licensed service/therapy animal. This is for liability reasons and for you and your pet’s safety. They will ask you to leave if you bring a pet in to the camp that is not a licensed service animal. We greatly appreciate your understanding of following the Camp rules.

In addition to vendor fees

vendors must also register and pay for any person coming into Camp Oakes to work in their site beyond the specified number for each vendor site that is included in the vendor booth fee, or otherwise attend the conference. See vendor registration form for more information.

A California Resellers License

is required to sell items. Operating without a permit puts the RTMC, Inc. at risk. If you do not already have a permit, you may apply for a temporary sellers permit. For information see: Swap meeters set up in the Swap Meet area on Saturday need not pay site fees or have a resellers license.


Registration for a vendor site must be submitted by April 18th, 2018. Any late registration after April 18th must be authorized by contacting Teresa Bippert-Plymate at the address below for special arrangements prior to making any payments or registration.

Vendor sites do not include lodging or meals for attendees. Any attendees beyond the specified number for each vendor site must register separately and pay for General Admission or Single Day Admission. Meals will be available from a menu, a la carte.

After you register, you will be contacted with detailed information about your site. If you have not received this information by May 14, or have other questions about vendor sales, please contact:
