Too many times ......sitting when I shoulda been standing .... not having my bow in my hand cuz i got tired holding it [:@]
Only once, for me. I missed an opportunity at a pretty decent 2.5yr old in 2005.....because I was exhausted and got caught sitting down whenI shoud have been more ready. He appeared out of nowhere(

) and there was nothing I could do.
Did it cost me a deer, though? Not really. I shot him last year as a 4.5 yr old.
