we have already done two wonderful road trips in the US, both were in September. We spent 2 weeks going from Boston to Bar harbor and coming back via inland New Hampshire. The second time we did San Francisco to Monteray and back via Yosemite. Both were much helped by advice from this forum.
Next year we are torn between doing a trip south from boston - Martha's Vineyard etc, or a trip from Pheonix or Las Vegas to San Diego taking in Death Valley, Palm Springs etc. We enjoy sight seeing , a bit of walking, vineyards and food.
Are these trips do-able in two weeks (judging by the length of some of the trips in this forum the answer must be yes) and which would would people recommend (I do appreciate this is a personal thing) but any advice would be v welcome.
