Do you have to be a member to shoot here? I'm from northern Illinois and this place is like 10 minutes from me so I REALLY want to shoot here

You can shoot in sanctioned matches at the club without being a member, but you will need to be a member to use the range otherwise.

If you want to join, you have to wait until the end of the year, and have a sponsor or two. It's a great place to shoot at, but I only visit and help during the youth shoot.
