Get out more. There's a reason Bi-Mart has an "outdoor" section. There are plenty of lower-income users of wildlands, particularly in the Inter-mountain west (WY, MT, ID, etc.) Why do you think Larry Craig (R-ID) was opposed? In a state that's 62% owned by the government and 43rd in disposable income?
Mabe we have a different view of fanatics then. To be a fanatic, it is not necessary to buy $5,000 in gear a year. All that is needed is a love of the outdoors no? Mabe if you go to smith rocks for your wilderness experiences or the muir hut you will see richies, but the fanatics I see, on a middle of nowhere trout stream aren't exactly looking down through the glass ceiling. Not all outdoor enthusiasts are climbers nor have to fork out $1000's every year to be in the outdoors 75 days a year.
