Hi. I am interested in doing some serious mountain biking in this area. I have been on a cross country road trip (helping a friend move) and will be in Pleasanton San Fran area this Tuesday. I need to rent/borrow a bike (i brought my shoes, etc) I kick butt. Anyone interested in taking me for a tour? i will be in area til next Wednesday. i will be climbing, hiking, etc... rental bike info would be helpful as well. thank you. veronica
p.s. I'm from connecticut, love single track.
