i agree with this, but for most of us that wont ever happen. my grandpa quit hunting when my dad made him, which was less than 6 months before he passed. if we hunted whitetails from a blind or something we would have taken him with. but spot and stalk hunting muleys was too much for him. my dad is mid 60s right now, and i hope i never have to make that call for him. he doesnt hike quite as fast as me anymore, but theres nowhere he wont go.When I see a deer and don't get excited it's probably time to hang it up...hopefully that's not anytime soon
