My main hobbies are bird watching and photography, combining the two for most of the time. My photographic equipment is manufactured by Olympus, which is a similar left field choice to Fiat, rather than one of the better known manufacturers.
Great idea for a forum thread. Now I'm going to have to settle down and think about what of the many things I do can be considered a hobby. It is tough because I still don't know what I want to be when I grow up so that means I am always trying new things.
If I get time to myself I like to build, modify and repair cars and also do other DIY stuff around the house. I sometimes take part in classic trials competitions, which involve on and off-road sections.
My big hobbies are traveling, riding my motorcycles, and tinkering with and restoring cars and motorcycles. I used to do some autocross and road course racing however have not done much of that in recent years.
Motorcycling, camping and flying. I built and rode my own bikes over a 20 year span, hiked the Alps with my brothers and rode all over the country on my bike, including a trip into Italy with one of my brothers.
