Name one thing...
How about "bumper skiing"? Never did it myself, but I was tempted a few times....
thats kinda how me and the wife decided to have kids
it was winter and we were out sledding in the parking lot
and by "we were out sledding" i mean that she was driving the car around the parking lot
i was on the hood, behind it, riding it like a sled while holding onto a tow rope
she send me up into a snowbank, and i had to let go of the rope to hold onto the hood to jump it
it was a fine jump, but i kind of miffed the landing
she said when she saw me get back up, all scraped up and covered in snow, she realized we were just having too much fun together and it was time to start a family
