I'm heading up to Ten Lakes on May 23. I have a permit and I am ready for any snow. It looks like the TM ranger station will not open until mid June, according to the Yosemite website. Can I just fill out a permit and leave it in the box like regular winter time or do you think I need to pick up my permit at another open permit office? I've tried to phone the permit office for the last few days and get a busy tone, I am sure they are up to their eyebrows right now!
Thanks
