How do you push a car up a hill?

It's not hard but you may soil your shirt. I once rolled a full-size 1993 Bronco packed with gear out of an arroyo. I was desperate. I started by pushing the drivers-side door and steering wheel but it began to roll backwards. I then tried running to the back bumper and pushing it from behind (probably dumb), but I could barely keep it in place and it cost me about 3 meters. I don t know why, but then I tried grabbing the drivers-side front tire. I rolled nearly 7000 pounds up a slope and saved my dog and I a cold night stranded in the desert. I then coasted down the bajada with no Power Steering or brakes listening to "The Cave" until I reached the highway, but that's a different story. Turned out one of the fuel pumps failed.
