Jerry, I went by Sierra and the retail shop is open. I think Gifford posted the hours.
Allyn, all I can say is if you think you might work on it, bring it and the tools to work on it with. I usually bring way too much stuff and never use 3/4 of it. If you have a stave horse or work bench you may want to bring it. Bring you some food, there will be some food for sale Friday and Saturday (gravy and biscuits, hot dogs, and maybe burgers). If there is anything you may want to trade, bring it. If you are looking to trade for something or acquire something, just ask around. You can get most anything you need for bow making and anything that goes with it. This list is kinda vague but you never know what direction your trip is going to take. I went to the Tennessee Classic once with all my bow making material and ended up knapping the whole time.
