Well, that's a bummer. Maybe Matt will confirm this if he goes there this weekend. Or soon.

I think the guy who posts on Craigslist all the time may have a fender, wherever Elkhorn Plain is - or whatever the place is called. I think that it's between Tacoma and Mt Rainier somewhere.

Ultimately you can cut the fender and make a flat flange mud flap like thing. I have a pair of Ranchero rear fenders I kept, The flares (stock shape) are not too bad. You'd for sure have to have deep tubs and probably still a means to lower the axle to get the wheels and tires off.
