ANGRY BIRDS REVENGE
Everyone has heard about the ANGRY BIRDS phenomena. Are you amongst the millions who have played ANGRY BIRDS on your phone - or your tablet? Have you a stuffed ANGRY BIRD sitting around your house somewhere? Now if you can find their four houses somewhere in Lethbridge, maybe they will help you find the pigs' house.
Each of the four bird houses (yellow, red, blue, black) will give you a piece of a puzzle - part of the co-ordinates that will lead you to the PIGS' house (GC5VD19). Good luck in tracking them down, but, please don't destroy the final find in revenge.
This cache has the "A" clue.
UPDATE - 6 Apr 2017 - Well the pigs have destroyed the yellow birds house. It is now a micro. The required clue is at the top of the new log.
