RE: crossbows will bring new blood!
If you didn't take any interest in your children when they were young, don't expect them to go hunting with you when they turn 12 years old.
All three of my boys went deer hunting with me on both Saturdays when they were 10, at the age of 11 they would go along with me on the first day and both Saturdays. I gave up the chance to harvest a deer to get them interested in hunting.
It's the ME attitude of today that is ruining hunting, do you want to tags a deer or have your child for a hunting buddy?
