This year, we are limiting our attendance to the first 70 persons who submit paid registrations. We want to avoid overcrowding to make sure we have enough seating, food, and drink for all.  Our intention is to offer our attendees a positive and enjoyable “boutique” experience.

IMPORTANT! As of noon on 8/31, we reached our limit of 70 attendees. We are not accepting any more registrations. There will be no onsite registration during the event.
