In honor of today's Opening Cermonies of the Olympic games in London, I'm happy to feature not one, but two different puzzle series with 60 or more puzzles each, (and some neat pieces of Geo-Art) in the United Kingdom. Here's a good starting place for each:
Red 01 - Sussex Olympic Rings
Red 06 Sailing Rings - Altius
Tomorrow we'll continue the Olympic theme with a puzzle in Canada's province of British Columbia.
