Congrats, Born2mtb! Sorry to read of your troubles (hopefully there were passengers on the bus who reported the driver's inattention - let's assume that's what it was).
My ride in this morning was near-perfect. A tad chilly, but that wears off pretty quickly during the one long gradual ascent that begins perhaps a block from our apartment complex. When I ride the bike to work I'm damn-near insufferably chipper for most of the day. For mood enhancement I've found nothing better. A thought: Maybe drug rehabilitation and depression therapy should be augmented with cycling? Silly, but...hmmmm...
