Call me gullable but I believe ya Birdman. Wearing some good work boots w/ vibram outsoles/bottoms, I once pushed a car into a different parking space w/ the doors locked, the car car in park and the owner gone as he was joy riding w/ some buddies. Did it right by me lonesome (although I'm no small guy still). Of course, the parking lot was covered in ice/black ice when we got there.
Makes you wonder why vibram doesn't make winter tires, lol
To the OP, I'd fill up on gas as well. Easy weight and traction aid. 36 gallons of gas comes in at approx. 220lbs. Every little bit of down force helping you get traction on a flat surface of ice is a bonus!
