I feel really good about myself these days, cause I'm down to only four bikes. I used to race (road- Cat 3) and still ride almost everyday. I echo Keith's sentiments about cycling being a big passion, next to photography and my family. My bikes are of several styles these days, but all have skinny slick tires. (If I'm going off road, I prefer to walk or hike, or ride a horse.) I have an old Cannondale road bike, a custom built steel frame road machine, and 1970 Colnago, all with Campy drivetrains of various vintages. These days, I'm also putting a lot of miles on a 1988 Paletti converted to single speed, with a fixed/freewheel flip flop rear hub.
I found that there's definately lots of overlap between users of old mechanical manual cameras and people who ride bikes. More, I think the same part of me that is attracted to the simplicity and the precision of a good camera is the same part that is really in love with the single speed bike, if not even the fixed gear. Then again, I would never give up my geared bikes, either.
One more thought- I'm trying to convince my girlfriend that we need to get a tandem bike. Anyone here ride one of those? How about recumbents? Surely there are a few serious weirdos among us...
