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

Never ever be embarrassed. I was the same.
I grew up as kid primarily duck hunting. I can only remember maybe making 2-3 deer hunts and squirrel hunts. Due to life changes I quit hunting at a very young age for years.

Later in life I wanted to start and get into deer hunting but I didn't know much about it. I asked a friend to teach and show me the ropes; up to even cleaning a deer. Sure, I felt embarrassed but one thing I noticed is he enjoyed teaching me all that he knew. I understand it all now. It was his passion, and what he enjoyed. Thus, he enjoyed sharing that.
Now, I enjoy doing the same.

IMO your easiest way to learn the ropes is to ask someone you know to show you.
