Esteemed Legal Minds,
I have a somewhat unusual question. I'm attempting to convince a public agency devoted to natural land preservation (i.e., a state Department of Natural Resources, or a Forest Preserve District) that it would be advisable to vacate several miles of unused roadway ROWs on their properties. These exist due to planned developments on the various sites from decades ago that were ultimately abandoned after the property was purchased by the aforementioned agency.
Am I correct in believing that, since these are public easements, or rather, easements for public roads, that a member of the public thus would have the right to simply camp out within the easement corridor if he/she so wished? And that they could do so without the approval of the agency which technically owns the land?
Thank you in advance for your assistance; I realize that this isn't the most common of queries.
