depending on terrain it can very greatly, if looking for an afternoon, as little as 50 acres can be fun, for a weekend it takes more. there used to be a place in harrison ark. by the old dog patch, I wheeled there before it closed it was fun, cant remember the size though. I wheel at my in laws place in marshal from time to time and like the terrain there as well.
good luck on your ventures, curious to see what your working on.
