I belong to several consevation organizations by paying an annual member fee. (Trout unlimited, The Nature conservancy and the Wilderness Society) I do this because I believe in conserving nature and wilderness. I don't make big bucks in my job so I can't respond to every plea for money to preserve this that and the other. I wish they would save the money I do give them by not wasting the postage and material cost to keep trying to get more money out of me. I think they should have a check box on the annual membership material that says "check here for no further solicitations during the year".
