Just got back from a 35 mile ride in town. Used some bike paths when they were convenient, but also tried bike LANES for the first time. It was a beautiful day, but I'm still not comfortable with intersections - it was nearing rush hour - I'm totally clueless on how to make a left turn on a bike when the road is 4 lanes in one direction (2 turning lanes, two straight lanes) - so that was highly stressful - luckily I managed through without too much risk (I think!). The hills were killers - I'm starting not to notice the smaller hills anymore, like I first did, but those looooooong steeep grades SUCK! I basically have to put 'er in the lowest gear - lay forward on my handlebars and move along at about 3mph (I have one of those upright comfort bikes). The knees are still killing me, but dang, still having a blast!
