Forgot to mention, for the second or third time, I REALLY missed 4x4. If the Big Bore wasn't there, the trailer might still be. Once the car was loaded, I pretty much couldn't move it.
With the wet slushy situation, I'm not sure 4x4 even would have gotten me out of the yard but I bet I at least could have turned around without more dragging.
Tire chains go back on my list.
