Wow! What an amazing range of hobbies/interests, thanks for taking part.
I guess my main hobby is the old car one. I a have a 1957 VW that I spent 7 years restoring, finished in '99 and still have. Put 15k miles on it, and it still looks stunning. Was magazine featured in 2000. I am presently restoring a '51 VW and also have a '69 Mercedes 280SL .....well my wife does. It was her reward for surviving 20 years of marriage to me some years ago. I have run a web business since 2003 as a hobby and make an restore some early parts for vintage VWs.
Avid do it yourself, project person, landscaper. Our home is an ongoing project/work of art. We have 3.3 acres of woods with a network of trails and I have an ATV which is a blast to ride.
Other hobbies are music and video editing, aeriel videography, photography, dining out, travel and racquetball (this is my 39th year playing the sport).
After retirement I want to get a modest camper trailer. In 2006, we went cross country in an RV with our kids and dog, in 6 weeks, 9500 miles, one of the best experiences of my lifetime. I want to do it again, albeit at a slower pace.
