LOL at your driveway story; I thought I was the only one who got winded by the ol' trash can relay.

My driveway curves and drops 15-20 feet before rising about 30 feet to the street, over a run of 500 feet. After the last downhill curve, I start running to get some momentum to carry me through the steepest rise. Then once gravity has beaten me, I slow to a walk for the last couple hundred feet up a milder slope.

That's all the exercise I get - my twice a week cardiac minute...

Bears, beets, Battlestar Galactica.
