What is one item on your bucket list? SUBA diving the Great Barrier Reef. This trip would kill a flock of birds with one stone. I’ve never been SCUBA diving, and I’ve never been to Australia. There are also amazing cities, and lush rainforest to see down under. And while I’m down there, I’m sure I can squeeze in a Lord of the Rings tour of New Zealand. The trip will have to wait, temporarily, until the whole family is ready to fully enjoy the experience.
What is your favorite place in Chicago? The Lake front trail, in which I will cheat and include Lincoln Park Zoo and Museum Campus. I lived downtown for a few years and could not get enough of running along the Lake. My wife and I would frequently take walks over to the Field, Shed or Adler and tour aimlessly around for an afternoon. Even now, we will often go as a family to one of the attractions and spend time biking along the Lake.
What is the best vacation you’ve ever been on? Just after graduating high school, I took a three week trip to Europe with my mom and older brother. We visited family in London and saw castles in Scotland. We visited France; stayed with friends living in the Black Forest in Germany; drove the autobahn; and toured Munich, Neuschwanstein and other towns across Germany. My bother any I finished out the trip with a week of hiking in the Swiss Alps.
