The Ponies helped pick the cache names...And they really like The Croods. Here is a small series in tribute.
This Cache is placed for SCAR2014 and should not be sought out until after 5:30pm on June 20th and any logs before that may be deleted.
Gran is the oldest of the Croods, mother of Ugga and grandmother of Eep, Thunk and Sandy. She is stubborn, and (like any mother-in-law) loves to tease/torture her son-in-law Grug.
