I borrowed the radiator cap from the Cherokee and went for a test-run. Once I was sure the system was holding well enough, I called Chrispy to see what he was up to. Low and behold, he and SillyPutty were planning a little jaunt within the next hour up to A&B.
No offense meant to anyone, I simply had no time to call an official run ahead of time. According the the Bylaws, this would not meet the criteria for an "official club run" anyway.
I texted ZMBEKLR to let him know what was going on. We met at the Conoco at Benton City around 11am and headed out to the offroad "parking lot". There, we aired down, met up with Chrispy, Silly Putty, another guy in a Grand Cherokee, and proceeded towards the canyons.
We successfully assaulted the last three canyons with before we decided we had enough of the rain. A few rigs were scraped and bruised, but we made it OK.
Gotta say; that little YJ of mine is a trooper!
