Are you saying there ain't no streams or rivers around your area? Eric Rudolph lived for 5 years in the forest... this guy in your backyard knows where he lives and will try to get some space but not until he feels secure and move south...
My guess is he will shoot it out. Although a 22 is not what you take to a gun fight. All I can offer is keep your tools close or locked up. Don't want to give him an opportunity to get a more powerful tool..
