I'm familiar with Cambridge. about an hour and a half from me.
I'm sure traffic was horrendous.......Friday night beach traffic is what it is called.
I'm glad he enjoyed himself, and you're a good girl for doing it!
actually, there was no discernible beach traffic, which surprised me. we spent 2 hours on the DC beltway trying to GET to route 50. there was an accident that closed all 5 lanes of it and we just had to wait it out. there was no other viable way to go, he went that way around the beltway to avoid the Wilson Bridge which is a nightmare bc of construction. once we got going on route 50 to annapolis and beyond, it was smooth sailing.
