**SPOILER WARNING** Normally when I do posts like this I take care not to reveal the name or location of the caches in question. However since this is all about the COG 10 Mega Event lab caches, it is hard to obfuscate those details. If you haven't found them yet and plan on caching near Tottenham Ontario, you may wish to skip this post.
This year was called The COG Cache Theory, and was based off of the sitcom called Big Bang Theory (if you are not familiar is about the hijinx of a group of 30-something ultra geek scientists, engineers, and one recovering wanna-be actress).
This proved to be a great theme as it led to a lot of creativity. The organizers release 40+ caches for the event, plus 8 lab caches, all of which were themed around the show - physics and comedy - what could be better? (not to mention the awesome thematic thread of lab caches themed around a show partially located in laboratories) The following are the highlights of a few of the lab caches that were placed.
The first is a ball pit (yes, Benignsource, its a "pit" :)). One had to find the right ball in the bit to grab the code to claim the lab cache (lab caches are claimed by entering a code word, not by signing a log).
