Interesting discussion. A couple points:
When looking at the stats, I'd like to decouple hikers and climbers..... they are really two completely different activities, with two completely different constituencies. It's nice for the state to lump these together because neither one buys a hunting/fishing license, or a vehicle/boat registration.
57% + 14% = 71%... whats the rest?
Anyone who advocates for an official "voluntary" fee that climber and hikers could pay into which would be dedicated for SAR (maybe you get a nice sticker or a patch to show your support) should realize that there things never stay voluntary...(see the Forest service day use pass). Do you really want to pay for a yearly license, so you are allowed to walk in your woods, ski on your hills, climb on your cliffs? Maybe you do.
While its true that climbers and hikers don't in general pay cash into a SAR fund. They quite often provide essential SAR services - for free. Without the volunteer outfits like, White Mountain SAR, Androscoggin valley SAR and many others, fish & came the forest service and the NH parks would be incapable of rescuing anyone. That's not to put the boot into those agencies but they just don't have the manpower, nor the technical expertise in some situations. In addition to the volunteer organizations, most climbers willingly volunteer their time to pitch in when the situation requires it. You climb long enough or often enough, and you've been there probably more than once.
