Contact Superior shooters supply and have them post a notice. Shoot me a PM if you want contacts in the NW Wisconsin area. I know several members of private and public ranges in the area. I also know of several people in the MN twin cities area that might be able to spread the word. Wish I was still in the area.
Tres, if you create a one page flyer that can be printed. I can drop them off at a few surrounding gun shops while on route. Just send it to me in an email.
I know it is a little late, but http://wi-force.org/ is the Wisconsin Firearm Owners, Ranges, Clubs & Educators Inc web site. You might be able to get info posted up there.
