I have access to 2 farms pretty close to me. A few years ago, I had some business cards made up with my name, address, phone, & work name printed on one side, along with a picture of a fishing rod, gun, & deer. On the back side were 3 personal references with phone #'s, my NRA#, B.A.S.S.#, & local gun club information.
If I happened to find a place with a pond or some shooting access, I would stop and ask if they allowed shooting or fishing. 9 times out of 10 they would say no the first time, I would hand them a card, and thank them for their time. I would always stop back about 2-3 weeks later, "just happened to be in the area", and see if they had changed their minds. One farmer said he would let me fish IF I did not leave any trash lying around like the person before me did. I didn't leave trash, also took some fish home, filleted them, and took them back to him to say thank you. After a year of allowing me to fish AND hunt on his farm, he introduced me to his neighbor who now allows me the same priviledges on his property. Last year I harvested a buck and a doe, processed the meat on my dime, and gave both of the farmers more than enough venison to last them thru the season.
That $12 cost for those 200 cards has paid itself back 100 times over . . . . . :thumbup:
Be safe.
