GPS drawing

I was reading my National Geographic Adventure magazine, and read about this site. GPS drawing was introduced to me in the book, _Fun with GPS_, and I was humored to see the concept mentioned in a 'big' magazine. Thought I would mention it here and at the IGO forums. The book author also talks about using a lawn mower for gps drawing. I've tried it in the neighboring churchyard, and I'm not good at it. I didn't think I'd need practice, but I did. Of course, I really doubt that I'll try it in the near future (whatever happened to spare time?). Do not look for juliecache as a gps artist any time soon.
