I did some searching, but didn't come up with much. Anyway, our MTB organization may be in the running to receive some donated Trex lumber to use on our trails. The question has come up about how slippery this stuff would be if used in this manner. My old deck was made of the stuff, and I loved it. I didn't find it slippery at all. Of course I never took my mountain bike across it either. So, does anyone have any experience using it, or something similar on their trail? Would it be good for supporting boards and not the tread? Thanks!
