Adventure does not always equate risk, but just the fact of living by the moment. I have an old shirt from The North Face company that has a view of some mountain range with the words below it "Never stop exploring". I really like it because that is what life is to me. We are put on this world for such a short time, that there are always someplace to go, some people to meet, and go explore. That, in a nutshell is adventure to me. Adventure is enjoying the best and the worst of life and being able to deal with both. Living in NYC could be adventure to folks from the country or vice versa.

Everybody has his or her adventure and that is one of the appeal.
