Park Way is incorrectly named. It is actually part of Upper Highland Way. Compare to google maps, which has the correct name.

Upper Highland does not cross Diablo Gulch. Google maps has this wrong as well, but on Google Maps it does not extend as far as shown here.

Alexander Drive is incorrectly named - it is part of Upper Highland. Also it does not cross Diablo Gulch or connect to Pema Osel Ling Retreat Center.
