Keystone Trails Association is holding their inaugural 25 mi Susquehannah Super Hike Sat Sept 12. Hike will traverse the lower Susquehannah, going south along the river from Otter Creek Campground on the Mason-Dixon trail, across the river, and north on the Conestoga trail to Pequea.
Like the trail, the registration fee is steep too: $50 (plus $4.63 s/h) before 8/22; $65 after 8/22; and $80 day of hike (makes ETE look like a steal). Includes deluxe school bus service to start point, snacks/drinks at checkpoints, picnic dinner at end point, T-shirt, and 1-year membership to KTA. See www.kta-hike.org to register and for further details.
I'm signed-up as have a few others.
