Hi - I'm new to this group. I'm the permit holder for two for October 1-4 Havasu Falls but my hiking partner just broke his foot. I believe my options are that I can cancel his permit until July 3 (90 days prior) and get half of his fee refunded or otherwise find another hiker to join in his place. Is there a sub where people are looking to find availability with other hikers for this particular hike? I know these are hard to get (especially for October) so I wanted to see if there was a match out there before seeking a partial refund.
