Caribou has partnered with PLUS1 so that $1 from every ticket will go to support GRID Alternatives and their work bringing accessible renewable energy technology and job training to underserved communities. www.gridalternatives.org All events beginning 10/1/2021 will require attendees to show evidence of their full vaccination against COVID-19. Full vaccination means 14 days or more have passed since the attendee has received a single-dose vaccine or the second dose in a two-dose series. Acceptable vaccination documentation may be a physical copy of a COVID-19 Vaccination Record Card, a digital copy of such card or such other proof as is permitted locally
