Using Seminars for Ham Radio

Early in October, I received an e-mail from our ARRL Section that announced an antenna seminar at a convenient location. The subjects of the antenna seminar were:

• Antennas 101 -- all about the basics of antennas
• Portable Antennas for EmComm -- antennas that you can carry easily and work in a variety of circumstances
• Round Table Discussion on Antennas -- answer questions from the audience

The reason this was interesting to me was because the seminar was not held in conjunction with a swapfest or any other radio event; it was just held in a convenient meeting location and hams (others?) were invited.This is an interesting approach to reaching out to hams and others.Why don't we do more of these? Or do more seminars at swapfests?
