I've always loved biking, but never really got serious about it. I won a "skilled driver" patch for my jacket at a bike rodeo in grade 5. In pre-driver's licence days I rode my bike everywhere. I bike commuted occasionally at college and at summer jobs. My first job out of college was about 15 km away and down a 300' escarpment (great ride in, tough ride home) and I rode the bike on occasion. Not sure why, I just did.
I've been at my present place of employment for 27 years (minus 1) and have ridden occasionally when I could. Some jobs I've had were construction type and I had to drive a car. As time goes by I have somehow managed to work farther and farther from home, so I have been doing a partial commute, seriously for the past year. It's been great and has really improved my outlook and health!
BikeForums has been a great source of information, especially for riding longer distances and all winter. The examples set by others on this forum have also been an inspiration for expanding horizons.
