I learned a valuable lesson when we picked up the permit. Apparently you have to re-confirm your permit two weeks before your entry date after you've already won it though the lottery and accepted and paid for it. Well, I didn't know that. The ranger dude was cool about it and said its not a problem and happens all the time.

Well, it's more complicated...
If you don't show up in time to pick up your reservation by the pick-up deadline (noon the day before), and you haven't re-confirmed it online, they hand out your reserved slots to anyone who shows up and asks for one. Slots confirmed online in the last two weeks are never given out to others.
Granola didn't say, but I will assume he showed up after the noon deadline. The reason it was no problem is that there are plenty of no-shows this time of year, so pretty easy to pick up a walk-in permit. On weekends (Friday/Saturday) late July and mid-August it might not be as easy.
