Spiral Curve Turn

I have laid out and/or built and experienced my share of circular turns, but also spiral and logarithmic. Recently I built a spiral 180 based on the Golden Ratio or Fibonacci sequence. More on turns here. First, I’ll say that I am a skeptic, but thought it would be fun to experience the Golden Ratio

Ask a Trail Builder

It’s not exactly rocket science, not even close, but there are some things I take for granted while curious outsiders might have serious questions on why and how trails are built and maintained. I assume other builders are in the same boat, or maybe shoes is a better idiom to roll with. I also assume

Hyperacuity on trails

Hyperacuity is our ability to discern very small angle differences and misaligned lines (see links below). Our vision doesn’t have to be good, and a vision test (visual acuity(sharpness)) doesn’t test this ability as the brain does a lot to amplify or help line things up or see misalignment. Sometimes I question whether I spend

It’s been at least 5 years since I had to close shop and move (more than once). To open the shop again I had to opt for not printing things myself. I might print a few select items in the future, but for now the printing and shipping happen in up to nine different locations

Pedal Strikes on Rollers

Recently failing with this because the rollers were too steep and abrupt, not flowy, the next logical limit is to consider pedal strikes as an option for roller peaks. A 100% strike-free roller isn’t possible because once you start to angle the bike from vertical/upright the pedal can strike the roller, especially if pedals are

A “straightforward way to curtail the spread of Lyme disease…”

tick populations and the risk of Lyme disease can be cut substantially by maintaining the deer population below about 10 deer per square mile. When the population is below four deer per square mile, even the secondary effects of climate change become irrelevant to Lyme risk. Yet, the Maine Department of Inland Fisheries and Wildlife
