Several conference events such as dinners and bus transportation have limited capacity so don't delay. First-come, first served. You must be a member of the Society through July 23rd to register yourself and then your companion(s). Cancellations are fully refundable through June 16th so if a desired optional event is currently Sold Out keep checking back for availability.
In addition, the area is a destination for Summer travelers so secure your lodging and transportation reservations immediately if you haven't done so already.
Local Wyoming and Montana non-member residents may register (below) for the portion of the conference in their area and recieve a membership in the society.
