Thanks again for all the replies (the helpful ones as well as the trolling ones)! I'll close the loop here with a mini trip report, I suppose.
Trail Angel Mary worked out great for my package drop-off and pick-up. She is truly an angel!
The region was blessed with some awesome weather (warm and dry) the week prior to and the week of my section hike. Mud was essentially a non-issue. I was happy to bring gaiters, but even happier to not use them
Deadfall on the trail was also not bad at all. There were a couple windy days, especially at Darlington Shelter, but not terribly cold.
No bears that I saw... haha. Don't think I even saw evidence of mice in the four shelters I was at. Just a couple mosquitos starting to bite, though.
There were a couple stretches in this section (particularly through some pastures near Boiling Springs) that were super flat that made for some quick days.
Crowded shelters in the area already. A handful on NOBO thru-hikers in the area, a bunch of flip-floppers, and some section hikers like myself (especially in Maryland).
Quarry Gap Shelter is the nicest I've stayed at. Thanks to The Innkeeper for the maintenance at this shelter! (Interestingly, this was the only night of the five that I was by my lonesome self.)
The ATC in Boiling Springs was closed due to staffing issues.
Harper's Ferry has a new (as of November-ish?) vegan restaurant called Kelley's Farm Kitchen, on Washington Street close to the ATC, that was phenomenal! Humongous portions, very fresh veggies, and it is operated by a super-nice couple. Open Thurs-Sun only, it looks like. A couple of NOBOs recommended it to me, and I would strongly recommend it as well.
