Read several stories about Kinsman's being difficult, but thought they were cake. Northbound over Moosilauke in May two years ago was icy going up and slippery wet with 2-3 feet of snow melt going down in a driving rain. Again, fun stuff. Interestingly enough, we ran into quite a few people day-hiking and overnighting in those conditions.
On a week-long trip last year, the northbound climb out of Crawford Notch ran me a bit ragged for a few moments on one hot August day after just finishing Franconia to Crawford on the way to Pinkham. Again, just part of the fun.
Remember folks, it's just walking. Take your time and it ain't all that bad.
