Yes that dang Jello effect, partly of it was the vibration from the trail/new tires and partly on the camera. Site lines are pretty bad this year, very wet spring and super hot summer everything is growing like mad (great fall harvest coming)
On this trail, Hikers walk in the opposite direction then the bikes, and for the most part with such poor site lines they are very careful to be caught in a blind spot. Hikers and bikers have a pretty good relationship out here, lots of trail work done together has helped. as for the horse people, that is a whole other story
I pretty much ride the same 4 trails locally, so I try to learn them in sections to keep the surprises down.
Yes a very big difference than ride'n in the west, one thing I didn't like about ride'n in Tucson, AZ (not quite Colorado) this year was just how dusty and sandy the trails were. We have a bit of sand here in Michigan, but its never more than maybe 5% of the total trail. I swear Tucson, AZ felt like rocks and sand were like 85% of the trail.
