I will be going to Denton Hill for the first time this year and see they have arials listed. Is this an event you can shoot at like the 3-d's, not sure how this works?

If it's like Comptons you pay for a certain number of flu flus that they likely provide.  There was a few problems at Comptons as fletching became wet and the arrows flew to far.  At that point they brought out the plastic spirals which solved the problem.

You bring and shoot your own arrows.

Someone volunteers to throw from behind a sheet of plywood.  It's cool having the arrows fly over you when you're throwing.

It's all self service.  No fee.
