You guys are in for some real fun years. My son started going hunting with me when he was 2 1/2, literally. By the time he was 5 years old, he was shooting a little kid bow (sorry, don't remember what) and a .22 chipmunk. When he was 12, it was finally time for him with a tag of his own. He drew a unit 20 pronghorn tag in Wyoming, and wanted to shoot his first animal with his bow, which at the time was a Browning, I think it was called a micro midas, or something like that. Anyway, he killed a pronghorn buck when he was twelve, and the next year he drew a deer tag and killed an 8 pt. whitetail buck with that same bow.
You guys are in for some great experiences in the coming years.
