My DH and i drove from NY to Maine for our honeymoon. We decided in advance we'd stop at any fun points of interest, but in general its a long drive so we wanted to keep to somewhat of a schedule. In order to avoid known traffic jam areas, and to be a somewhat straighter line, we had a route planned that didn't keep us simply on 95 the whole way.
Well we missed an exit. We were still in the correct general direction but not following our mapped out route. DH was so angry (he doesn't deal with last minute changes, especially errors, well) until he realized our new route, really only about a 20 minute detour all together took us through Lowell, Massachusetts. Well one of DH's absolute life goals, a bucket list item, was to visit Jack Kerouac's grave in Lowell.
It was an easy detour, and a perfect sunny, brisk but not cold autumn day with some leaves on the trees and some fallen on the still green grass; the cemetery was lovely. It was such a happy accident (well... as "happy" as anything involving a grave visit can be!)
