Yes, money does not fall out of the sky. However, I do not think it is appropriate to use parking fees collected at "undeveloped" trailheads primarily used by wilderness users to pay for new boat ramps, for example, or elaborate "labor day camping sites" on USFS land. I hate to hear that the USFS is hurting for money when I see a brand-new enormous log cabin-style ranger station in Detroit, OR. Now I'm not sure this is happening or not, but if it is, I think it is wrong. Again, I pay federal taxes to cover this.
