Way to go Dliz. I too have had good success in PA in the last 3 years with my bow harvesting 3 of the 4 biggest buck I ever shot. Not quite as awesome as the ones you have taken but in my neck of the woods they are impressive in their own rite.
But I too spend my time looking, scouting all year long and hunting every chance I can get. This year I totaled 126 hours in the tree stand before releasing my arrow.
