On a random search trailism.co came up! I have nothing to do with it, but I guess they liked the name. It’s not a stretch to think they came up with the name independently, it’s not that original, but damn if unique domain names aren’t hard to come by. At this time there is no […]

Four years ago I did an e-bike post that was poorly written in hindsight, or there wasn’t too much insight. I don’t know that version two is much better this time around, but there are some new thoughts: E-Bike (E-Motor Bike) “Problems” On Trails

In 1987 Roger Bell was way ahead of the trail building curve with a handful of other trail contractors when he started Bellfree Contractors with two of his brothers and some nephews.
