Hi abracapocus,
Unfortunately no I haven't gotten started. That's a good point - I'm basically just looking for something much simpler - I've done biking in the past and HATED changing gears - especially over mountainous terrain, even though I know I couldn't have not had multi gears. My route, which I've sort of laid out already, doesn't really have a lot of hills that I couldn't climb on one gear. I'm sort of a mountain goat anyway, so these little hills in Atlanta don't bother me.
I'm glad to know you're loving commuting in Atlanta. I'm concerned about safety issues more than I am about hilliness!
