I don't do anything that would get me in big trouble with the cops, but I've done a couple of stupid things during vacations.

Harvard has a lame schedule where the finals for fall classes are in the middle of January and they give you a week off between finals week and the beginning of spring semester, and I always went with my friends to New Hampshire or Vermont to go hiking, skiing, and ice climbing. Junior year we decided to be ballers and do a 3-day hike through the Presidentials which is an easy walk in the summer but it can be real tough in the winter due to the weather.

A couple of days beforehand the place got pounded by snow and it was like -25 degrees up there so if we were smart we would've canceled the hike and just gone skiing but we decided to go. The only really dangerous part was when we had to cross a steep snowfield in order to get to a mountain pass, which I made an MSPaint of. The last couple hundred feet before the pass, it was like a 45 or 50 degree slope on slick snow right down over the edge of the cliff. It was painstakingly slow going. Take one step, shift your weight, plant your ice axe, and repeat. If you take one mis-step where your footing isn't secure, you'd probably be dead unless you manage to catch yourself with the axe which is never guaranteed to work.

I also got snow stuck in the big toe of my boot which gave me pretty nasty frostbite, my toenail and all the skin on my toe fell off. If it got much worse I might've lost the toe but luckily I just had to walk around like a gimp for couple of weeks before I could walk on it again. Here's the MSPaint BTW.
