The Hatfield McCoy marathon does not look impossibly daunting of a task…
Granted:
1) Flying Pig was 6:30am vs. Hatfield 7:30am start
2) May 4th was unseasonably cool.
3) June 14th is 6 weeks closer to the heart of summer.

Obviously, the noise/granularity of the Flying Pig elevation map exaggerates the elevation totals, or vice versa, but Hatfield/McCoy still looks about even with the Flying Pig.
