Visited the park today. Superman is indeed running both forwards and backwards. I did both. In fact, as I was prepping to ride forwards, the backwards side launched, and as it was coming back down, we launched, with us passing it at the curve. That was super awesome to see!
They also had a crapload of food locations open that are never usually open at all, including Twisted 'Wiches, Ace O' Cubs BBQ, and the Snack Shack in Bugs Bunny land--the later of which I have never seen open, ever.
Mask enforcement is a joke. They're supposed to be wearing masks inside, but I'd say literally 50% of the people in the main gift shop did not have a mask on at all.
But the big news: Tatsu is testing! It's still not open, but I figure it won't be too much longer now.
