Light rear end might the be culprit there, I had that happen once in college with the Pontiac. I need to go up a steep hill (paved) but it had been raining, my rear wheel spun and could not get traction. I had to go around and approach that friend's house by a different route.
What kind of tires do you guys run out there? "Summer slicks?" My daily driver's tires are near completely bald, great gas mileage this summer but no place for the water to go if it rains.
Getting new tires next week. 4 years on one set!
