Where in Iowa would you like to start?. 2 rags I like to read are (put the name of the state here) GAME&FISH, and Fur-Fish-Game. They help and give a starting point in contact information.
I don't know if your familiar with this site, but many here use the "can I help you with your varmint problem" approach to gain deer hunting privileges later. Your kind of like the guy that walks into a bar to rob it. Poor bast#$& doesn't know it's were off duty law enforcement hang out.
