Another comment from a neighbor which emphasizes my point:"Interesting—the chains will make it much harder for kids to get their bikes around, and will force them to ride on Alpine across JS and Sand Hill. I don’t like riding there as an adult, and it’s really risky for kids at rush hour in the mornings!
Stanford promised us a path to replace the one we had, and this allowed them to get the right hand lane added so that Stanford commuters could get to Campus Drive West. WE WANT A PATH! and we want it now
