For every Winter Solstice event, I try to hide the same amount of caches as the date of the event. Now in its 8th year, this is getting more difficult so I succumbed to this- the trail hides along the Friendship Trail.
Welcome to the Out Of Ideas series. 
These hides vary a bit because hiding them, all the same, is mind-numbing but none are difficult unless the snows make it so.
