Lectures are open to the public so you certainly don't have to join the AIA just to attend them. It's too bad that you'll miss the Egypt one, but we are also very excited about all 3 of the other spring talks which occur on Wednesdays and Thursdays.
Hello Judy and welcome to the site! We're happy to let you know that our big Egyptian talk for the year is fast approaching (on Feb. 16). Hope to see you there!
Best,
Jayni
