on bicycle commuting

I am getting the route and routine of my bike commute down and wanted to comment on a certain aspect of it that came out in a discussion with friends the other evening. Specifically, it is that, when commuting on my bike, almost every day/night, I see something or someone that I would never have run into were I in a car. These are not necessarily "big" things, just experiences that make life a little more interesting. I'll use this last week as an example. I commuted on Tuesday, Wednesday and Friday. Tuesday I was on the road earlier than usual because I was having dinner with friends and it was light my entire return ride. About a third of the way through, near UCSD, I noticed I was cycling with a young woman who, when I asked her said she was riding home to Pacific Beach. I offered to show her the best way to go and we shared the ride for about 10 miles or so. Didn't ask her name and I'll probably see her again out on the road. Wednesday was my usual later evening ride. At the base of Mt. Soledad, as I was heading up Muirlands Road, I could see a young woman walking down the sidewalk to my right. She perked out, "Wonderful evening isn't it?" in a friendly sing-song kind of way. I responded, "Good evening", and then it got weird. She came walking at me quickly, "Why won't you help me, Sir?" she barked. My bullshit meter went off big-time and I zipped to the other side of the road and pedaled uphill as fast as I could. She continued, "What are you doing, Sir?", to which I replied, "Riding away from a crazy woman". I finished my ride wondering what the hell I had just experienced, coming to the conclusion that spring-break LSD or X had juiced the poor girl into some kind of dementia. Thursday, not much until very close to home when a guy ran out of his house squawking, "Dude, where did you get that light?", "You light up the whole street!". After multiple "Dude" -peppered exclamations from the guy (I think he had a couple drinks in him), I showed him my light (the "light & motion" brand headlamp that has changed my life and DOES, in fact, light up the whole street) he seemed satisfied and I pedaled up the hill. Admittedly, differing experiences -- but all interesting and none would have happened had I been insulated in my car.
