In reply to VPJB:
I don't think it's a huge issue.
If the article is correct it says "the park will issue an unlimited number of free permits" (for big wall climbing)
That seems way better than the system for Half Dome that's been going for many years now. I was travelling through for 5 days in 2015 and tried in advance in the ballot. Didn't get a ticket so resorted to the scramble up the front to the shoulder and on to the cables instead.
It's all a bit of a pain but with busy National Parks we can expect more and more of this. That's life
