RE: Roanoke, Va/ getting involved??
The first place to start is with your friends and your friends parents. Do any of them either hunt or shoot. I don't know of anyone who has experiance that is not interested in introducing new people to the hunting and shooting world.
If you don't know of anyone who hunts, you might want to try finding people who do a lot of fishing. Many fishermen are also hunters and shooters. This is a little more of around about approach but it should pay off for you in the end.
Bottom line is that you need to begin by letting everyone knowthat you're interested in hunting and shooting and start networking yourself.
Have fun, be safe and good luck!
