If you get it, I strongly recommend cutting just a few walking trails. Then, focus on all the other things that need to be done, and there will be many. They all take time. Live with the land for a while and understand it. Watch the wildlife and how heavy rain affects it. That's a pretty place as it is and wildlife needs cover to support the myriad of insects, birds, rodents, snakes, varmints that it takes to make for any kind of hunting. Cut all that down and you will loose a lot of the interesting things on the property...and it will take a long time for it to grow back the way it is, if it ever does. There are parks in town...people go to the country because it looks...like country!!! Damage from land clearing has been disastrous in terms of erosion and loss of habitat and wildlife. Yes, we need to eat and tractors can help that....If you plan to fence the property, why not spend your energy on that and get a couple of goats to do some clean up...you will be amazed at what they will do to 20 acres...and in short time, too. When they have finished, or you are tired of the goats, you can eat them.
