I'm in Alabama and there are plenty of rural woodlands, pastures, etc. that are rented out all the time. You can try farm listings as well. Are you interested only in the mid Hudson area? I know there are quite a few old, former camps in the areas around the catskills. Good luck on your search!
PS if you're into saw milling there are some great units on trailers such as the Norwood or woodland mills line.
