New Technology for California Bike Trip

Last summer on our Vermont Bike Trip we relied almost solely on the turn by turn directions of the Adventure Cycling Association map for navigation. Jesse brought his Tom-tom but luckily we only had to use it twice the entire trip. This summer in California we are upgrading our navigation techniques by using GPX waypoints in addition to the ACA map. The waypoints provided by ACA are pretty cool...they provide turn by turn directions and also list the services (gas stations, restaurants, motels) in each town along the route. Check out the waypoints for our trip on a Google Map:
