The estimate I get is 27-28 taps per roll that would mean you needed 18-19 rolls.
Deer season opened here in Vermont yesterday, my older sister decided she wanted to hunt this year, so I took her to "my spot" and set her up on Saturday. I sat in the secondary spot. About an hour in a young buck made his appearance but did not allow her to tell if he was legal. He ran off. So we went back this morning. At a little after 9:00 I headed back to her spot to call it a morning, she was looking the other way pretty seriously so I stopped and waited. After a few minutes I took a few steps toward her and she jumped. She started giving me crazy hand signals. At first I thought little Jimmy had fallen in a well...lol. She gave me the hand on top of the head...meaning antlers. and then motioned around behind her. So I snuck back around and up. I heard the deer start to run so I ran straight ahead about 10 steps, stopped and listened. I thought he was going to run down through the open maple so I ran ahead to see if I could see him and he ran up the hill right to me.... 8 point 150lbs
