Today I took my Jeep all the way up to Shirley Peak at the Alta Sierra (Shirley Meadows) ski area. My dad and I drove all the way up Rancheria road and then came back home down Poso Flat road. We hit up plenty of side trails along the way and put my Grand Cherokee’s Quadra-Drive and low range gearbox to the test. It was definitely a fun afternoon of 4×4 off-roading with my dad.
