I commute by bicycle every day, and thank my lucky stars that I live in Portland and have that option. Most people are not so fortunate. It looks like the improvements I would suggest (web-based bike route finder, better connections, more bike lanes) are already being planned. My only ongoing concern is bike safety education. Our couple of sunny days last week brought out a lot of bicyclers who don't normally bike; I saw lots of people dressed in black on black bikes with no lights or reflectors blasting through red lights and stop signs, or going the wrong way up busy streets. I guess there is always Darwinian selection to reduce that population, but probably obeying traffic laws and wearing bright colors would be less messy.
