At quick glance, yes it seems that the data on the
RR Wiki: Blue Ridge Parkway page is also in the DB, but please notice that the Wiki page represents the whole park, whereas the information in the DB is split across two DB pages, which are the
DB Page: Federal (NC) page, and the
DB Page: Federal (VA) page. On each of the DB pages, you will need to scroll down to the
"National Park Service" section to find the
"Blue Ridge Parkway" listings.
Edit: As you will notice, in-general, the Wiki might also list some older info that might have been deleted from the DB, or unconfirmed data that is not yet ready to be submitted to the DB. In the case of the BRP Wiki page, it also lists some older info that is no longer listed in the DB.
Hope this helps,
