Sounds like You have very good spot,its just the Bucks are older and wiser and are nocturnal right now.The Bucks are probably still in their Bachelor Group so they will be traveling together for a while...once the weather changes or it gets closer to the Rutting Season they will split up and probably end up sparring/fighting each other for the right to breed the Doe's.As long as You have Doe's in your area the Bucks will be around chasing them,if your goal is to shoot a nice Buck don't kill off too many Doe's.Sooner or later the Bucks will be traveling during the day time making rubs and scrapes and checking for Doe's....thats when they mess up and You'll get a shot at one of them hopefully!
