I am not sure how you would search for such parks, but instincts tell me they are mostly only going to exist in some of the snowbird destinations. Like another poster pointed out, I would bet the insurance on such a feature would be out of this world, especially in a park with a large mix of guests (which means children). I couldn't even imagine the size of a lawsuit should some unsupervised children get into a woodshop full of power tools and a few human limbs joined the limbs from the trees. On top of that, the noise wouldn't be welcome most places, so it would have to be a park with a lot of acreage so they could put such a shop a long way away from the sites. In my opinion, unless your idea of woodworking is whittling like Jed Clampett, expecting to find facilities that would support your hobby as you travel the country seeing the sites will probably be an expectation that will not be fulfilled.
