I'm a member at the Buffalo Gun Club.
http://www.buffalogunclub.org/ That is a trap shooting facility only. It is very laid back and there are plenty of great trapshooters there that are most happy to help somebody out. It is a bit of a drive, they are probably the cheapest in the greater Twin cities Area. Ask for Sally if you're ever there, she's a great lady and she's kicked my butt many times.
A much more fancy facility is the Minneapolis Gun Club in Prior Lake. That one is probably a bit easier to get to from your place.
http://www.mplsgunclub.com/. It's a beautiful place with a restaurant and all, they do skeet and sporting clays too. I think they charge about $9 per round but they will assign you a range officer who is very friendly and helpful.
We are also eagerly awaiting warmer weather to shoot some trap. Let us (me or SwedishBabe) know if you want to go, if we can (not always easy sometimes) we will gladly join.
