I am selling Caltrain monthly three zone pass (zone two and four) for my friend who just knew he needs to travel out of county for the rest of this month. You can use this pass in any of the zone 2, 3 and/or 4. The value of this pass is $179 plus $3 of clipper card. I have all document of the pass purchase. I am only asking for $90. Price is still negotiable. Contact me if interested.
