Last Wednesday I teased the subject of today’s episode of Math and Musings, writing that the Pennsylvania cities of Lancaster and York have several things in common.

Still stumped?

There are two big ones.

One, both cities were at one time temporary capitals of these United States.

Related, they are two of the 10 cities that have housed the Declaration of Independence.

As of last week Franklin and I had been to eight.

We’ve now been to all 10.

Yeah, nerdiest vacation of all time.

Enjoy!
