I’ll be heading home soon after a wonderful time in Philadelphia. The food here is awesome; I loved my “fancy-schmancy” hotel (Loews Philadelphia); and I bought nearly everything there was to buy in the gift shops, which I now will have to try to cram into my suitcase. It will be a physics lesson….
Most of all, I will miss my “up close and personal” chats with science teachers. Normally, I only get speak with you on the phone and e-mail you from my office in Arlington, Virginia (right; don’t you love those file folders!)

Have a safe trip home, and I hope to see you next year in San Francisco!
