Hrmm, not sure if I am going to be able to make it this year. Have you ever thought about changing the weekend? It's my wedding anniversary weekend and I'm not sure I can convince H to travel to Philly with me. Plus its a super busy time at work. I might be able to head down for the day on Saturday and take the 66 home.
We have this happen almost every year. One year we did change the weekend for one AU member who could never come the normal weekend we have it. Then, that member never showed, anyway, so the committee decided we will always leave it the same weekend every year.
And, as Dave mentioned, you can attend as much or little of the events as you want. From where you are located consider bringing your husband and just meet us for the dinner in PHL on Sat night. Get a nice hotel room and have your anniversary in Philadelphia.
