I am glad that you enjoyed yourself. That Philly chapter is a top notch group and claims a few AOII bigwigs among her members. The only other things that I would do at this point are to 1) write a thank you note to the chapter president and 2) contact HQ and let Sherry know that you met the ladies. If someone gave you her phone number, I would follow up with a casual lunch or coffee in another week or so. If no one gave you her phone number, that's OK too. The first meeting of the year is always such a worldwind and sometimes a little thing like that can get overlooked.
Sending you good thoughts...
