Suggestion by sayribaer
I want to suggest the geo-art "Les super-héros" by skincell.
A series of caches, building a superman logo. There is a total of 50 caches (37 mysteries, 13 multis). The riddles are easy, but if you expect another 50 film canister thrown into bushes, you are wrong. Except for a few, all containers are well camouflaged into the environment, creatively hidden and good craftsmanship work. We had much fun doing the tour (and it took us way more time than expected).
It is located just east of Montrél, QC, Canada.
