Love the R/C planes. My dad used to build and fly many years ago. He won a number of awards for his planes at shows in Detroit and was part of a flying club. He still builds the occassional one, but he can't fly them anymore.
I am debating getting into modding my car. For now it would be more esthetics, nothing for performance as I am not mechanically inclined. Lots of folks consider that a hobby.....
I've heard it can become quite addicting, so I've been doing lots of research and trying to decide what I want to do.
We also do a lot of camping in the summer, I love to read when I can find time, hiking, cycling.
