Here’s what I sent to Ryan Snyder, regarding my routes and destinations. Send him your routes too! (update 2009-02-26: my emails to this address have been bouncing, others have not had problems, but another address for Ryan Snyder is: ryansnyder [at] ca (dot) rr (dot) com.)
As several other people also pointed out, a big problem with Pasadena’s bikeways currently is that they pay very little heed to which roads are actually pleasant and safe to ride on. Here are some notes on the routes I use, and avoid. I’m an experienced cyclist, and have always used a bike as my exclusive mode of transportation (didn’t get a driver’s license until I was 25…). I live at 200 S. Parkwood Ave. (near the intersection of Del Mar and Allen).
