I recently retired from a local fire department in South Fort Myers, FL. We covered a popular biking trail, John Yarbrough Linear Park, as Rails-to-Trails, have limited vehicle access. We have in the past pre-planned each section of the park for emergency vehicle access points and path obstructions, ie pedestrian bridges only.
Each section has been designated by intersecting roadways that allows us to place the caller’s location for emergency access points as per our response plan for that section of the park.
