Sometimes it just happens. I think all of us have been busted. It will happen again. I wouldn't worry too much about it. Not questioning the way you hunt, but 13 or 14 feet is not very high for bow hunting. I personally don't like being less than 20 feet while bow hunting. Preferably 23 to 25 feet if possible. You did say you had good cover though, so who knows. You weren't swatting mosquitoes, were you? I have been busted doing that before. Thank God for Thermacell now.I can't believe deer season opens so early there. Is there a particular reason why? Too many deer? South Carolina seems to have very liberal hunting seasons. Just a side note, if you come on here wondering why something happened, you have got to expect many different responses. Nobody is questioning your hunting knowledge or capabilities. There are many knowledgable hunters on this forum and they are just trying to help. Some are here to bash and start arguements, but most are not. Good luck, I'm sure you will eventually score.
