In May, I spent some time in Montreal, which is a fantastic caching town. Lots of high-quality caches, including a TON of puzzle variety. The perfect cachecation for a puzzle monkey like myself. The first cache I found when I arrived in town wound up being one of my favorites. So of course, I immediately made plans to steal the idea. All the credit here goes to Montreal cacher and creator of fine puzzles: mountaintop.
The cache can be found at:
N41 43.###
O88 16.###
This cache has been placed in conjunction with an event to welcome another cachecationing puzzle monkey: Celebrate Dutchlandian's 1000th U.S. Find!, however, I'm releasing it early to give folks a chance to figure it out before the event.
You can validate your puzzle solution with certitude.
Congrats to cubdad7 for the FTF!
