Geocache Description:

Tri-Cities Geocoin Challenge takes geocachers around all four of our cities exploring new locations while finding newly placed geocaches. After finding all required geocaches and completing the passport you will earn this year's 2016 geocoin set. Since there are a limited number of geocoin sets, you can earn one per house hold only.
