ALL ARE WELCOME. We encourage visitors, and would enjoy having you join us for a meeting or a field trip.

Meetings are lively proceedings, with a featured speaker or a special forum as well as reports from the various committees, announcements, and general field notes.

Club meetings are held at the Academy of Natural Sciences, Philadelphia, PA (Directions to the Academy). Bimonthly, on the first and third Thursdays at 7:30 p.m., the season begins on the third Thursday of September and goes through the first Thursday in June.

Before meetings at the Academy, an informal pre-meeting dinner with the speaker is held at “Asia on the Parkway,” 1700 Benjamin Franklin Parkway, Philadelphia (corner of Ben Franklin Parkway and Cherry St.), a few short blocks from the Academy. Everyone is invited to attend. We meet at 6:00 in the back room of the restaurant; look for us at the long table there.

Pre-meeting Dinner: Asia on the Parkway

After the meeting, we usually adjourn for drinks at Cherry Street Tavern (129 N 22nd St), three blocks from the Academy.

Post-meeting Drinks: Cherry Street Tavern
