Back on December 6, 2015, I placed a bison tube in a tree in Aldergrove. It was published two days later. When MulderClan! arrived for the FTF hunt, he found this:

Calamity! Disaster! Won't somebody think of the children?!
I placed a new bison tube container in a nearby tree and the cache was finally found.
In commemoration of that event, I am placing a new bison in a tree, this time in Fishtrap Creek Park.
If there are people on the trail, please wait to search until they have passed you. Please respect park hours and do not attempt at night. Park is open from 1 hour before sunrise to 1 hour after sunset.
