Put chemist (+1) as attending. I bought tickets last night SNA-ORD-LGA arriving LGA at 5:15PM on the 12th. We should be able to make it. I'll update when I have my hotel plans. If we don't make it or are late, that is because we got delayed going into LGA. (We haven't been to LGA).
We are going to the Brooklyn event on the 13th and my wife (and I) are looking forward to a nice meal at the Soup DO.
