Old Town Ramble and Ride Festival goers interested in winning an NWT Diamond and other great prizes must visit a certain number of businesses to get their "passport" stamped. The passport is part of the festival schedules available at all participating businesses. Once again, courtesy of the City of Yellowknife, the grand prize is a Polar Bear diamond valued at roughly $2,600. Completed booklets can be dropped off at Down to Earth Gallery or Gallery of the Midnight Sun prior to the draw at 5 p.m. on Sunday, August 1.
