Hey, never mind! I found the link in another thread. Looks like Burning Man pulled the link to the eventbrite page, but you can still go there and buy water if you have the URL:

Just got 10 gallons!

I got a ticket through the Burner Express Plus offer, where it's tied to riding the bus in. I made proper arrangements for my bike and whatnot, but I mistakenly thought for some reason that the offer included water. I just now saw on the FAQ page that we need to buy it in advance, but now the ticket...
