D'oh!

I had to go into Boston this morning - I had a meeting in the Back Bay, so I parked at the Pru. But I made one crucial mistake. It's been so long since I had to drive into town that I forgot about validated parking - had I stopped and bought a cheap knicknack, I would have paid only $7. But I had to fork over $28 instead. A $21 mistake. Rats.
