As the young guy in my group, now 36 I can tell you that it I got sick of hunting with the old farts. Once my dad was no longer hunting with us I reserve my camp time to work weekends and projects but hunt elsewhere. The old guys hate change, only like doing the same old things they've been doing for years regardless of outcome. They're super cheap and not very welcoming to visitors. The politics of a group also get old, who does what, who said what, who will/won't pitch in etc... I love hunting and have much more fun by myself or with some good friends my age and with the same passion/desire and ability to try new things.
