COVID-19 Precautions

We are putting the following precautions in place for the health and enjoyment of local participants as well as staff and volunteers:

  • All local attendees will affirm that they are fully vaccinated prior to attending. We ask non-vaccinated members of the community to join the virtual experience.
  • Local attendance will be capped at 200 people, perhaps fewer. In particular, the auditoriums will be at no more than half their seating capacity.
  • All meals and breaks will be outdoors.
  • We are working to provide live viewing screens outdoors. Any participant is welcome to watch any talk from the outdoor area if they prefer.
  • Poster sessions will be virtual-only. Local attendees will participate from their hotels/accommodations in the morning before coming to the venue for talks and outdoor socializing. We are working to have technology or assistance available for anyone who might need it for the virtual poster sessions.
  • Afternoon social activities such as discussions or roundtables will take place partially or entirely outdoors in the tent.
