This is my favorite conference so far, and that’s saying a lot since I’ve worked at NSTA for 12 years! Even the weather is cooperating—it couldn’t be a more beautiful time to be in Philly. Yesterday I walked around downtown, and when I wasn’t dodging revelers in green, I took in quite a bit of history. It seems like the whole city is ready for NSTA. Even the Philosophical Society is having a special Darwin exhibit. And how fun are the trolleys? (Although a word of caution is in order—don’t wear a slippery coat or you’ll slide right off the seat as the driver rounds a corner…) I’m already hoping I get to go to San Francisco next year!
