Just an item of possible interest. There is a run from Quesnel, BC, a town of about 8000 south of Prince George, to Barkerville, a restored gold mining town east of there starting tomorrow and winding up on Sunday. They are carrying mail and a part of the event will be
Canada Post unveiling the design for their dogsled mail commemorative (due sometime in March).
