Hi John. Hope you got moved ok.
RE: East-West Trail
I have one for you, the Ouachita Trail.
This trail is 223 miles long, running from in the west, Talimena State Park (Oklahoma) to Pinnacle Mountain State Park (near Little Rock, Arkansas). Most of the trail (192 miles) is within the Ouachita National Forest. The remaining 30+ miles are on private or state-owned lands in central Arkansas.
There are various side trails to view points, camp sites, water, and intersecting trails. The 37-mile Womble Trail is the longest of the "side" trails, and is open to hikers and bikers.
The trail is marked with traditional 2x6 inch blue paint blazes using the standard blazing conventions. There are 21 trail shelters, which were built and maintained by the trail club "Friends of the Ouachita Trail - FoOT". Here is a link to their web site: https://friendsoftheouachita.org/wp/
Here is a link to the US Forest Service page for the trail: https://www.fs.usda.gov/Internet/FSE_DOCUMENTS/fsm9_039448.pdf
Finally, here is a link to general information for the Ouachita Trail: https://en.wikipedia.org/wiki/Ouachita_National_Recreation_Trail
There are several video series on YouTube about this trail.
If I wasn't so involved with trying to finish the remaining 1165 miles of the AT, I'd love to try this. Based on all I've read, it is well marked and maintained, and is lightly used.
I welcome any comments regarding if the reader has heard of this trail or has walked it?
