I biked to school in the "old days" from Kindergarten through 6th grade. After that the school I went to was too far away. I also biked all over my neighborhood - to the pool in the summer, to the library, movies, store, piano lessons, etc. etc. Then I stopped because I just wasn't cool.
As a high school junior in the EARLY '70's, I bought a Schwinn 10-speed - my first road bike! Loved it though the shifting was AWFUL and I never could get the brakes to stop squeaking.
I got married, had kids, and stopped riding again (note: I was never a "real" rider - recreational at best and even that is a stretch. I wasn't what you would call a natural athlete).
When my son was in college (University of VA) he got me into mountain biking and I did that for about 8 years - until I was tired of leaving body parts on trees and rocks. I switched to road biking and haven't looked back since. After gradutation from college, son moved to the High Country in Colorado and has since relocated to Denver - where he continues to race both road and mountain bikes.
X-husband rode some but is somewhat of a weenie ( did I just say that???). Almost new DH was cycling in Idaho before I met him....
So....I would say my son got me back into cycling.
