I bought a small parcel a few years back that is almost entirely encumbered by a conservation easement. The way it's written it's forever and will never expire. And it's pretty limiting too (no cutting trees, no atv riding, no agriculture, etc). Buts is all wet Creek bottom that was left over from a subdivision.
I paid Penny's on the dollar for it, and now have a small tractor in town minutes from my office I can bow hunt.

One day I may get a lawyer to look into my options on the easement because I would much rather it was not there. A little time with a multcher head and I could make that place nice to hunt
