Yes the I-81 valley is an amazing travel corridor for nearly 500 miles without any major cities, and hence, litte APRS density. Yet it is the BACKBONE of the East Cost and with the only mountains in the east, we should have it nailed with APRS. But I do think there must be some old WIDE's because I cant believe we should have those gaps. And we are going to be dependent on this path for the Appalachian Trail Golden Packet event! www.aprs.org/at-golden-packet.html
In particular I hear that there is a digi (KW4FM-3) on Sand Mountain in Wythville, yet in the months we have been planning the AT event, we have never seen it on the APRS-IS. Also, the callsign does not have a valid Email address on QRZ. My suspicions are that it is an obsolete WIDE and without an IGate in range, it is not being heard beyond its own footprint. (though on my plot below, there was good coverage through Wythville from digis very much farther away.
We really need to get in contact with the owner. He will play a key role in the AT trail project. Here is the web page on that part of the 14 hop link.

Yes, statistically, one every 10 minutes (ive calculated it during my long lonely drives every xmas).. But with only 5% being APRS, then that is once every 3 hours.

Oh please! We really need to get that San Mountain digi upgraded, and we need to get his email address so I can work with him to make sure that site is set up for the Appalachain Trail event.

Here again was my plot through the I-81 Corridor:
