One of my fondest memories traveling is from the first time I went to Madrid, Spain. I taught students all the English needed to play soccer so we could spend our class period outside kicking a ball around. As thanks they took me to a bull ring and convinced the managers to throw me in and "fight" a bull! Really, it was just me running away from a small bull while everyone else laughed... There's a video of this somewhere, but you'll never see it.
I get hopelessly lost without a smart phone (Yay GPS!). I get this from my dad. We once went biking around my childhood neighborhood and got lost. For 6 hours.
I like to go into the city alone and talk to random strangers. I've met some wonderfully interesting people this way-- a former surgeon general, the guy in charge of designing Disney theme parks, a stoner who believes he is god, someone who thinks they can cure arthritis with copper wire and gemstones, and the list goes on...
I have a collection of hundreds of Spiderman comics that I started when I was 8 years old, but I haven't seen it in a few years. It's in my parents' basement somewhere in New Jersey.
