I love holding writing workshops with engineers, businesspeople, and consultants, and have done in 12 different cities in 3 countries so far. I wrote about it here: http://stc-techedit.org/corrigo/tag/christa-bedwin/
I have taught lots of other things too, from yoga to math and chemistry to horseback riding and chainsaw use (yes, I'm pretty good with a chainsaw, just in case you wanted to know. And a horse. Maybe not at the same time, though my great-grandmother was famed for being a fine shot from horseback -- particularly at the coyotes during calving time... but that's another story).
