I have confidence you guys can stop this if enough of you write in. I recall during the early 1990's there was a plan to start charging $$$ to people on bicycles entering Mt. Diablo State Park in the SF Bay Area. A bunch of us riders wrote to our state legislators, and signed petitions, and were able to successfully block the measure.
If it were the feds doing this, you'd have no chance, but state-level your voice can often be heard, and your voice matters to elected officials, especially if you get enough other people to join in. Good luck bros!
