I agree that that whole section of the Bay Trail needs to be fixed. Sometimes the trail is along the north side of Bayshore, but sometimes you have to cross the expressway to the south side. Biking past Facebook is confusing and dangerous in both directions. Then trying to bike from Facebook to Palo Alto involves a number of confusing turns through heavy traffic. The Menlo Park Bay Trail is pretty disappointing compared to the Bay Trail in Palo Alto and Mountain View.
