RE: How long
The evening of opening day during my third year of bowhunting is when I had my first oppertunity to harvest adoe, but I missed her at 20 yds. I didn't follow through and I shot right over her back. Since that day, my pre-shot motto includes the phrase, "Follow Through".
I passed on a small doe the next year, my only chance of the year, so I didn't get anything that year either.
Finally on the second day of my fifth year hunting, I got a solid oppertunity. Thethree point came up from a river bottom at 15 yds, and I plugged one through him. That was my first archery deer and first buck ever. Not a bad way to start off my archery hunting career.
