I'd be ok with a $10 "do it all" stamp that allows use of public stuff like ramps, public hunting areas, public piers, etc.. I work with several people who go bird watching all over the state on the weekends. They spend a whole day using places like Killdeer Plains, Magee Marsh, and Ottawa Wildlife Refuge without ever paying one red cent. They get damn near offended when Ive suggested they pay a yearly stamp fee to use these places for bird watching. Then i point out that they'll drop way more than that in gas, food, etc for one outing to enjoy what us hunters/fishermen mostly provide for them.
