Besides, Miatas, Track and AutoX or other car related interests, what other hobbies do you have?
We may find some of us share more than one hobby. ;)
Another hobby of mine is reading, watching and otherwise soaking up history. Specifically I have a strong interest in WWII. It started with a high school thesis on WWII aircraft but really took off after reading Band of Brothers by Stephen Ambrose.
My wife and I share a hobby of going to estate sales. Even my daughter, who has been going since she was an infant likes finding vintage toys. My wife looks for vintage paper for her scrapbook hobby and I head straight for the garage looking for tools and such. I also look for WWII books. We used to collect mid-century modern furniture but since down-sizing we had to cut back on that.
Coolest find was a hidden letter in the case of a drill I bought. The letter was from a Sgt in WWII to his parents. Enclosed were a German soldier's war photographs from the invasion of France, some personal letters on Nazi letterhead signed with the salutation "Heil Hitler" and some postcards from Prague. Obviously they were captured from a German soldier by the U.S. Sgt and sent home. I'd like to think his father hid the letter in the drill box to keep it from the mother as some of the photos were a bit graphic. The photos were of a dead French soldier, dead horses, burning tanks, crashed airplanes, destroyed bridges and towns and strangely a baseball game. Did the German's play baseball?
Along with that, I like restoring or re-purposing items found at the estate sales. I recently picked up an old steel roll-around cart for $10. A bit of paint and new hardware and it looks like new. It is a perfect tool cart.
