Route advice From I-81 S, east to Concord (Charlotte) NC

X2 on I-77. One long grade almost at the VA-NC line, down the eastern continental divide. it has great views much of the way down if the weather's clear (drive, and let the copilot record it for later ;)). Nice welcome station in NC just past the bottom; I've overnighted there several times a few years back. Traffic thickens bunches after the I-40 crossing every time I've been that way.
