Dear Mapsters,
Please know that these new USGS digital topo maps also include
inaccurate road files. The roads in our area included ancient roads that
had been closed for 100 years, as well as timber skid roads symbolized
as dirt roads. Neither can be used by cars.
Just a heads-up that the gov't roads layer is poor to worse.
