Damn it, you made day 3 backwards. Damn old people and technology.
Ok, here are my ideas.
So Wednesday night I would have to slab to Cincy then Thursday turn around and do some slab and basic highway to get to Charleston. I think I will slab to Parkersburg Wednesday night and have fun on the northern section of 16 Thursday morning. I will meet you on your day 1 route near Charleston. Probably in Racine where 94 hits 3. Well done, I really like 3. It's not a crazy twisty road, but it is very curvy and goes through some very interesting areas. But you skipped 16 south of there. That is kind of a must do road when you are in that area. That would put us in Marion that night probably.
Day 1 suggestion.

So I started us in Marion Day 2 and got us on the BRP very close to where you had us starting. We could just continue down 16 and pick up BRP a little later also. Or cut over to The Snake if you want. I don't really care about that road, it's kind of short and a PITA to get to and get out of. And you wanted to hit that eastern section of BRP which is the best section imho. I also added a detour to Day 2 near the end by Little Switzerland. No way we can drive past 226 and 80 and not ride them.

I changed the end of Day 3. Same to Tellico then cut north along part of the Damn Dam tour and then we can hit Devils Triangle at the end and stay near Rocky Top.

Day 4
F'in slab home.
Hope I didn't blow up your plan too much, I have a tendency to do that. Your phone number still end in 82? I can call and we can chat about it.
@Pauly you in?
