Jeff,
If you're looking to come down for the weekend, it's easier to set up shop in the morning than late in the evening, however Thursday nights are always pretty fun at the classic. That's when most of the weekend crowd arrives so everyone is out making bows and hanging by the fire.
There's going to be a lot of people and vendors there, a LOT. The main "campground" area is mostly RVs and Campers, but there's plenty of room down the trail for tents so you shouldn't have trouble finding a spot.
We've got a full shower house and porta-johns set up for the shoot so you're covered there.
Starting Friday morning we open the kitchen up for concessions for breakfast and lunch. We do sausage patties, sausage gravy, biscuits, fruit/energy bars, etc in the morning, and we do burgers, chips, hot dogs, cheese burgers and chili cheese burgers (with grilled onions) for lunch, along with candy bars and sodas and stuff.
That kitchen runs breakfast and lunch through Sunday.
The bow shop fills up fast, we've got over a dozen vises to work on bows but they're going to be in use from sunup to late in the evening, so get one when you can, or if you've got a setup for your camp that works too.
If you're looking to make a bow, you may want to hit up some of the people here that bring staves to see if you can reserve one from them, but that's up to you. All of the vendors will be setup by Thursday evening so there's plenty to buy.
BRING CASH. We don't take plastic at concessions (we also sell bagged ice) and while most vendors do, some don't. Cash is king at the classic.
Other than that just plan to have fun. It's always a good time, everyone is friendly, and there's always a fire going around the camp.
