re: Embarrassed about this, but can you start hunting later in life?

Tell one or two of them exactly what you're saying here. If they're good dudes, and most outdoorsmen are, they would love to help you out. Make it clear you're not looking for a free ride or to get in a camp/lease membership. If you're invited to a camp bring steaks and cook them. Bring whiskey/beer and share it. Bring paper towels or TP or a few cases of water and leave them. Help clean up and wash dishes. Pay for gas coming and going & do not take no for an answer. Ask questions and pay attention. You will soon have more invites than you can accept. Good Luck.
