Here's a simple multi-cache for your enjoyment. The posted coordinates are for a sign at the edge of a park named for a mayor. Go there to find the third digit in the final year he served. Fill in the blank for the coordinates for the final cache container, a red bison tube on a tree:
N 40° 41.322′ W 80° 18.6_6′
Bring a writing device, and happy caching!
