Congrats on hopping the brook, and finding the first cache, now on you go!
Last year, right at New Year's Eve, the CtB! team realized Western Island Pond was frozen enough to get out on the pond and the island, and we hid "BYOB", referring to "Bring your own Boat" or "Bring your own Bombardier" ski-doo, depending upon the season you want to go for that hide.
This one is "BYOB", referring to "Beside Yonder Old Bog"!
This is the second in a series of several geocaches on a traditional hiking / ATV trail, which could make for a great winter afternoon hike and several geocaching finds for your map.
The cache is a 500mL wide mouth screw-top container, hidden in a winter friendly manner. Discretion is our motto at CtB!, and while this one is only a few metres off of the trail, the hide spot was chosen to be out of the way of a passing ATV... which actually occurred during placement. An ATV went by slowly, and no one knew there was a geocacher right there. 
This cache contains the coordinate "B" for the mystery cache "YYT Airport Run!"
