After visiting the Original Stash Plaque for find 100 this summer, I was determined to finish out the trifecta before the end of the year. Decided to make a day of it and knock out Geocaching HQ and Mission 9: Tunnel of Light back to back on the same day.
Had a great time visiting HQ and seeing all the amazing trackable artifacts. Seeing Mount10Bike's coins along with the all the partnership tags were a high point.
