All times are MIT (Eastern Standard Time, UTC-5). Resolved based on the time that the first team completes the final challenge (usually called "finding the coin"), as announced in either an E-mail from the running team or at wrap-up on Monday. (Note that campus is closed to visitors during the early morning hours; if HQ announces that a team has completed the Mystery Hunt up to the final runaround and is only waiting for campus to open to officially finish things and be declared the winner, we'll use the time of the announcement.)
