This is definitely a challenge for me too. Where are you located? You could try the Alpine Mentors Unofficial Facebook page but that seems like slim pickings for most locations. Several of my good alpine partners don’t live near me but we can meet and climb together when our schedules align. I have partners in Leavenworth, Bellingham, Driggs, Sacramento, Portland, etc.. I met them when we happened to be at the same climbing area or through internet forums.
I live in Bend, OR. I can’t make the Ruth this spring but I have the last week of March free and no committed partners yet. Plan A is Canadian Rockies. If that’s a possibility for you shoot me an email samuelj(period)bedell at gmail dot com
