The nature of the approach via McNamee Road is indeed an issue, less so because of the trestle but because of people pulling out of a formal parking area with limited vision up and down the narrow winding road. They'll have to figure that one out. (But it's really no worse than parking off of Newberry Road - a busier road by far - for the Wildwood.)
To be clear, right now no bikes (and no pets, of course) are permitted at any of the properties (although I saw the ubiquitous loaded doggie poop bags at both Burlington and Ennis).
Well, he can't check it out unless he's a member of the Northwest Trails Alliance. Members only - Rocky Point is a special agreement between Weyerhaeuser and the NWTA (and even the NWTA doesn't have access when Weyerhaeuser is logging). Like other Weyerhaeuser properties, it is closed to the general public.
Even with the development, I suspect the neighbors will be able to find plenty of quiet time to enjoy the spaces. Metro, whether you like the agency or not, does have an obligation to taxpayers to provide access to most of its properties. Burlington, or at least part of it, was slated for a private housing development before Metro purchased it.
