The Obama Presidential Center used to have three hard-working tower cranes. They were a glorious team. Alas, we’re down to just one now, but it’s doing yeoman’s work on the center’s Museum Tower.

Dear Mr. President (#44),
Time is running out. You don’t have much time to give me a call so we can arrange a tower-crane climb together, now that there’s only one left. I’ve got steel-toed boots. See if you can get your developers to lend us hardhats and vests.
