Pros: . Plenty of solitary pedaling . Into focus and then stark relief viewpoints throughout . Gradual climb . Plenty of desert grandeur . Straight-away bike lanes feel good in the densely-populated PS portions . Drivers seemed pretty respectful . Good distance & workout Cons . Got a cactus thorn puncture . One of the overpasses is very narrow with fast traffic and limited visibility . Bike paths aren't what I'm used to: smooth, straight-away, rail trails . Bike paths are dangerous at times due to all the perpendicular roads . Gene Autry Trail bike lane is a shoulder, very poorly paved, alongside 50mph traffic . Gene Autry Trail path is more like a sidewalk . Some of the pavement on the course is the pebble-and-oil type; very numbing . Some of the pavement had beach-like, white sand that extended all over part of the shoulder forcing the rider very near fast traffic
