I started in BMX bikes (in the 70's) then road bikes (in the 80's) before getting my first MTB in 85 (Peugot Orient Express), stopped riding for a while, then got another MTB in 95 and rode for a while before stopping again in late 90's. I just recently (2 years ago) bought a new road bike and ride it as much as I can. I switched to the road because I can roll out of my garage and go anywhere I want to go for a ride. With the MTB there was always the whole production of loading all the crap up in the car and schlepping it out to wherever, then back again. I realized that the reason I kept falling out of the MTB riding was the amount of a time suck it always ended up being.
