Here's my best one that I placed last summer, and only has a few finds. It's in Central Newfoundland, and is a puzzle cache of sorts:

I still have an unfound one on the small island of Ramea, but it is a 5/5 cache.

Theres one in Corner Brook that has been published for two years and hasn't been found. I looked last summer, and couldn't find it. If you do, tell me where it was. lol! I think it's called "Gorge'ous"
Have fun
