I'm also a new member, since April this year. Usually there in the evenings myself. As said above, normally out there by myself during the week.....well my 9 year old son is usually with me. My wife, my son, and I all went this past Friday earlier in the morning, most people I had ever seen out there but even then there were maybe 15 others out there total.
You do have to have referral sigs on your application to join. I didn't know anybody. I showed up at a meeting and there were at least 100 members there. Around 17 of us new propects. Before the meeting even started some other members came around and signed our referrals. After that you schedule a walk around with a club officer. If you want your wife to be able to shoot without you (immediate family included in membership, and they don'tcount against your 2 guests), she needs to go through the walk around with you. Its a guided tour, covering rules, safety, etc. You both will be required to shoot to prove you know how to handle a firearm and practice safe muzzle discipline. If she passes the walk around with you, then she gets a membership ID just like you (no additional) and can then go on her own at anytime. She also gets to take 2 guests as well. So you both can bring a total of 4 guests out there. Don't bring people you don't trust to follow rules though as your membership rides on their behavior!
