Glad to hear your going to make it out Brian! I am no longer in MN and wont be making it. You can start posting here, also on the loaner/borrow forum, you can also friend the MN 3gun group on Facebook.
Even if shooter115 cant make it you will still do well showing up at the shoot with ammo (100-150 round of each: 223 (no steel core ammo!), 12ga (trap loads) , and pistol ammo). Lots of guys bring spare guns and are always excited to show them off/loan them out.
My first 3gun shoot I had a 20"AR with 3-9power hunting optic, a 3.8" 9mm and an 870. I spent a ton of time reloading the shotgun at that first event but I learned the safety rules and had a blast, i have been hooked ever since!
