Buglady, best wishes for the best outcome...and from a former migraine sufferer who's cured for good, if you want a suggestion in that direction I've got that too.

Ride in today again cool and cloudy and breezy, but made much nicer by a pleasant encounter with a fellow commuter about halfway in. We rode a few blocks together before our routes diverged, yakkin' about the weather and what to wear and this and that...it was kinda like meeting someone from this forum in real life! The other pleasant thing is, I'm getting better at this. Successful commuting is a combination of so many things: planning, dressing right, choosing a route, knowing when to merge, knowing when to make a move, agility on the bike, being able to spot the opportunity where you can make that turn without buzzing peds in the crosswalk or getting tangled up with cars. I watch other bike commuters (16 today that I noticed) and see how they handle things, and try to emulate the ones who seem like they're successful. The large majority are successful, which really tells you something given how diverse they are.

In sum: bike commuting is cool.
