Well I'm confused more than ever now. I'm still not sure how caches can be approved just by assuming one has permission to place a cache along a city highway and or on public right of way property.
The reason why I'm asking these questions is because I actually work for Public Works in Nashville. I've had extensive conversations with supervisors in the streets and roads division. They all have told me geocaching can land me a hefty fine if anything is stuck to or placed on city property without permission. This includes guardrails , off the city owned roadway , light pole skirts , water drains inlets , guide wire micro's etc. I guess I'll just stick to the hunting part of geocaching. But then again , they also told me just lifting up a light pole skirt can get you into trouble. Yikes ! Might as well stick to park hides. :/
