For those that have climbed Katahdin or Mt. Washington, how useful are trekking poles? I will be going to Washington in late June and Kathadin in July. I've heard mixed reports via TR's on their usefulness for both, some say they unnecessarily get in the way and are a hindrance while others swear by them. Plan is for Huntington Ravine for the ascent on Washington if the weather allows and Lions Head on the way down. Of course the knife edge on Katahdin if possible.
My girlfriend and I have a lot of experience in the Hudson Highlands and elsewhere and are going to make the jump to bigger objectives, but we've never used poles before. We're both pretty fit with no knee issues and good endurance.
Side note - will we be missing black fly season in NH by going in late June or will it still be a problem?
Thanks in advance.
