I just talked with a staff member at congressman McDermott's office about this. He was pretty up front with me and said that even though alot of people are opposed to this its really not going to get any attention unless something as public as the opposition over the IRS access happens (which is unlikely since most people are entirely ignorant when it comes to understanding this program). He suggested that the best course of action would be to start adressing the issue for next year, as there is a way to override it, via handwritten letters to your representatives and the key leaders stated above (the staff member said he doesn't pay much attention to pre-printed statements, postcards and email; I don't really know about phone calls though). He did mention he had no hopes of this being changed untill we have a chance of changing the balance of power in congress in two years. I wouldn't take this as discouragement but OnTopofPoo is right they are really just revisiting this bill because of the IRS issue and nothing else is planning on being discussed. Personally I'm going to keep up the calls over the next few days but then after than I'm going to start addressing the issue via letters to hopefully get some action next year or at least continue getting people educated on the topic.
On a side note if you are not sure how you stand with respect to fees for public lands I'd suggest reading Ken Wright's book Why I'm Against It All.
