My husband and I are planning a road trip in April 2011. We wish to start in San Francisco, rent a convertible and explore for 8 days. We are not locked into any particular location and will fly back to Boston home base from wherever our final destination is. We would appreciate any input about possible routes that encompass scenery and things to see. We could go north, south, or east. It doesn't matter. Of course we do want the top down on the car so that may influence where we may go. I am inclined to want to head north but I am concerned about weather as we will be traveling in April. Any thoughts would be helpful.
