A few more:
• Despite my parents owning various ski boats for the past 20+ years, I've never learned how to waterski.
• I've never ice skated
• Never played on any high school sports teams (played a lot of basketball, just not on an actual team)
• Never have done drugs (alcohol on the other hand is an entirely different story)
• Never have gone hunting or fishing
• Never have owned a gun or even fired one
• Never have been to Canada
• Never have been to New York, Seattle, San Francisco or Boston.
• Never actually changed my own oil in a car that I own. Now, motorcycles on the other hand, all of the time.
• Never have seen "Caddyshack" or "The Big Lebowski" all of the way through
Looking at this list, I think I'm going to make it a checklist of things I am going to do in the next 2-3 years (except for the high school and drug stuff)
