Adam, did you mean Franconia Ridge?
I was on Mt Washington from Friday to Sunday and found my beloved microspikes to be useless. On Friday, the combination of rain and snow created a cement-like mixture that balled up pretty quickly to the microspikes, rendering them useless. After a few minutes of use, I had balls the size of softballs built up and no traction. At the lower elevations, there was a thick layer of smooth ice just under the wet snow. Off-trail, I'd say that there was 18 to 20 inches of snow, and deeper drifts in places. Our solution was to use snowshoes for traction, although I suppose crampons with anti-balling plates would have worked too. All season, I've had a love affair with my microspikes, but I really witnessed their limitations this week.
Also, we used our axes quite a bit on our summit day.
I should mention that we crossed a pretty sketchy snow bridge at one point on the lower section of the Huntington Ravine Trail, and I was really glad I had my weight distributed on snowshoes. I have some illustrative pictures, but they're on my other PS so I'll have to add them later today.
ANYWAY, March works for me too. I'd be happy to join either group if the dates work for my schedule.
One other gear option is rental. My *understanding* is that the EMS in NH and NY rent plastic boots, crampons, and ice axes. I'm not sure if you have to be part of one of their official programs, but I've seen the gear in NH.
