A friend and I are planning a run at a leg of the WBCDR from Rim Rock Lake to Ellensburg this Saturday. We have info from RV ranger that Bethel Ridge is clear, kind of!! NEVER TOO OLD just was kind enough to install a set of Shinko 705's on my Wee. Now I am wondering what you guys air down to for the dirt. So far, I haven't found it neccessary to lower the pressure on the rides I have done thus far on the Wee.
