Completed Section 2 and part of section 3 on May 9th. Temps ranged from low 40's at night to 80 one day. Dealt with 2 strong weather fronts. Threats of strong winds and possible tornado resulted in one 12 mile day and a motel stay. Weather apps, including radar, are essential. Dealt with winds a lot because of the weather fronts. Variety of head, tail, side winds, sometimes gusting over 30 mph. Mostly from North and West. Rode in rain 1 day. I've done transamerica so it's definitely no worse than that.
We encountered dogs a few times each day but most of them did not come out into the road. The few that did come out were easily scared away with our Walmart boat horns so we had no dog encounters that were a problem. btw, the small Walmart horn lasted through sections 1 and 2 before it ran out of gas going into Corydon our last day. The usage also included tests and demos at home. I've tried pepper spray, squirting water, sticks and some sort of inaudible to humans dog repeller but nothing is as easy and effective as the boat horn.
We had no problems with drivers on Section 2. In fact, we were surprised by how courteous and friendly KY drivers were.
Scenery and road conditions were great on section 2, much better than section1.
Very few warmshowers so camped most nights. If you call Cloverport, KY police (listed on map) they will let you camp at "boat ramp" but there are no restrooms. Make sure you camp at the one in the downtown waterfront area. The boat ramp camping off Hwy 105 is very sketchy. Heard stories of meth labs, gunfire and other problems around that boat ramp.
Overall, Fulton, MS to Corydon, IN was a fantastic trip. Great scenery. Very friendly people. Lots of history along Ohio River.
