NARGS will use its best efforts to comply with all public health requirements in the locality, state and country of any event or tour that NARGS hosts, and NARGS expects all event and tour participants to comply with all such public health requirements as well. These rules and requirements may change closer to the date of the event or tour, and NARGS will use its best efforts to notify participants of any such changes that it is aware of. Depending on the circumstances of the event or tour (and as listed in the pre-registration or registration information), NARGS may also require participants to take additional actions related to public health to be able to register for or attend the event or tour. Participants understand that they will be required to sign a form of waiver and release for events and tours that NARGS hosts.
