Specifically, additional parking enforcement and signs along Portola Road near the Windy Hill parking area has resulted in increased protection for cyclists (and the occasional pedestrian) and prevents us (cyclists) from being forced into traffic lanes by a line of illegally/poorly parked cars.
I've biked in this area for 12 years now, and it is my sense that respect for others and adherence to the law is increasing generally. Efforts by cities and towns in this area are an extremely valuable part of that increasing respect and compliance.
I'll keep doing my part by stopping at signs, yielding to pedestrians, and keeping my lights flashing, but I wanted to share my gratitude and the extra measure of joy I feel when biking through Portola Valley. Your efforts are noted and greatly appreciated.
