I am posting this on behalf of Rick and Liz Weber. I'm posting this as an announcement only because it's not open for debate. I strongly encourage everyone to be gracious and comply and not do anything stupid to put our access to Muir Valley climbing at risk. Thank you.
Effective immediately, "Victory Whippers" are no longer permitted in Muir Valley. Recent input from climbing hardware/gear manufacturers, highly respected climbers, and AMGA guides overwhelmingly supports this decision.
