We headed toWrights Lake to spend the night and be the lost subjects in a Search & Rescue Winter Training Exercise. We left PlacervilleCA about 6:20pm on Friday night and hit the snow at about 7:45pm. The road to WrightsLake is not plowed in the winter and starts at 5500 feet elevation at this point the snow was 3 feet deep. We put our jeeps in 4 wheel drive and let some air out of our tires. My Jeepster weights about 5800 lbs and I run a 36-16.5 15 tire with 2 psi in the snow. At about 10:00pm and 6700 feet elevation the driving started to become more difficult and very slow. It is only 2 ¾ miles to the cabin we are going to stay in and it took almost 7 hours to get there. There was lots of winching and shoveling with a few tires needing to be put back on the rims. The cabin is at about 7000 feet elevation and the snow was about 6 feet deep. We had to dig down to get the door open and check to see if the chimney was clear to start a fire in the stove. We only got about 4 hours rest before we need to start back for the training exercise. The trip out was a little faster but still required winching, shoveling and a few tires to be mounted. The trip was a great challenge, a test of equipment and driving skill.
