I'd like to register at Katahdin Spring Campground in the very early morning of my Katahdin summit and hitch a ride to the Helon Taylor trailhead (Roaring Brook campground) so I can hike the Knife's Edge at the start of my SOBO thru-hike next year. How feasible is this? Are there any shuttles or public transportation operating in BSP? Any tranportation options to the other trailheads?
I have found nothing so far speaking to this point. Any reference websites appreciated.
Am I correct that I must register even though I aim to summit and be SOBO outside the park on day 1?
