The DEP only recognizes roads that have a right of way on them as being legitimate roads. Historic roads such as stagecoach roads and whatnot that do not fall under the criteria of being "roads" will be closed. The rationale is that they were never intended for motorized use since they were built before cars were invented. So when you say that ~500 miles of roads are now closed, the DEP's answer is that most were never roads to begin with.
Can anyone else see "fault" with this line of thinking? Think transportation, be it a road, trail or path not the mode of transportation. Under the DEP's definition would all roads purposely made for motor vehicles then be off limits to all other modes of non-motorized use? Were any of these "right of way" roads once stagecoach?
What is a "right of way" road? Have these roads only come into existence since motor vehicles?
Unfortunately the wording and thinking is ripe for a lawsuit and a lawyers dream. The "powers that be" are able to inflict injustice with no cost or consequences to them but costs much to change. The irony is that private funds must be raised to fight for change while public funds are used for defense. If effect tax payers seeking change are helping fund the fight against themselves.
As for the little known "newly released" natural preservation zones, would these by chance coincide with the areas now commercially exploited by the PPA?
