In the end, we decided to cook a lobster feast with another couple at their house, which was a good compromise: ie, still doing something, but nothing requiring too much energy/big crowds/expensive fixed menus/etc. And it was a fun, chill night overall! It was just what we needed. (Although, I'm not sure we needed 3-pound lobsters per person!)
Here's Jeremy with the lobsters before their "bath"...and then once they were actually in.
Did you guys do anything fun? Anything legitimately crazy??
