Walked down to Riviera to the back of Montara, where the imported TIger traces begin to deviate significantly from the Yahoo images, and from reality.

I'm still working on using the gps, so this is more of a dry run for me than an official trip. I got some experience setting marks and observing the roads. Noted the end of the county roads. Found a house with three (!) driveways. Learned a few subtleties of Maemo Mapper.
