Drove 100+ MPH on non-divided highways as a teenager--had some scary close calls. Also took a lot of foolish risks riding motorcycles and ATV's while not wearing helmets or protective gear (like it would have saved me anyways!) Did some extremely stupid stuff shooting guns and almost hit a neighbor lady with a bullet ricochet. Blew up a dry ice bomb outside of the Cannon Center (didn't cause any damage) during my freshman year at BYU--I didn't even grasp the fact that this would have gotten me tossed out of BYU and arrested had I been caught. I'm glad that I did a lot of growing up on my mission.
