I'm doing a 200 mile section heading north from the Hurricane Creek Campground/Troutdale area in Virginia beginning on May 22. My starting point is a 2-3 day hike north of Damascus, and I see that Trail Days ends on May 18. It's not going to change my plans, and I don't stay at shelters very often, but I'm just curious about how big of a crowd I should expect. I'm picturing a mass exodus of northbound hikers clogging up the trail all leaving town at the same time. How long does it take for that crowd to spread out and get back to "normal?"
