The monument has recently been painted and the guardrail fence updated.

The monument is minimalist, but few tri-state boundaries are marked with a monument, and even fewer are right next to a road.

Monument is very aged. and the white base is corroding. Now has guardrails. If you geocache, there is one we found by fluke!

This is a very small marker in a field.

The tri-state monument used to be in the middle of a road, but cars kept hitting it. After several run-ins this monument was moved off to one side. You can stand at the new spot and the old spot (as long as there's no traffic).
