From Ed Faron, Midstate Trail Supervisor:

This afternoon I visited and walked the Midstate Trail north of Bond Street with the owner of the land who showed me “the hiker trip wire”., It is actually A THIN YELLOW STRAND OF ELECTRIC DOG FENCING, which is flush to the ground and has been stepped over and on by hundreds of hikers  for the past several years.The first strip of dog fencing is at  the edge of the lawn in the gravel  area and the next strip is embedded into the lawn. The land at 7 and 9 Bond Street is located in Leicester and not in Spencer.
