RE: What other hobbies do you have?
I take an occassional break from building and flying RC planes by building and flying Control Line and Free Flight planes. At the next level is building HO scale train cars and locomotives. I vary the monotony with model ships, especially the ship in a bottle types.
I love listening to music, especially early folk, jazz, and classical, which lets me multi-task with the music in the background. And at work, I often take walks through the local county Metropark wetlands with my camera.
Luckily, most of whats on TV turns me off, so I have lots more time for the worthwhile things. Luckily, my wifwe often joins me in these pursuits.
