Ann Althouse discovered that the first few posts of the day contained some reference to lobsters, and made a theme out of it for the day.
She then googled "lobster" and discovered that today was the first day of the Maine Lobster Festival here in Rockland. Serendipity was on a roll today.
Here's Althouse's lobster themed posts.
And here's her specific post about the Maine Lobster Festival. Along with some interesting and fun discussion in the comments, in which mine appear towards the end.
Not only was serendipity on a roll, but so was lobster! (Ba-doom, crash!) Thank you, thank you, be sure to tip your waitress.
