Minor updates from SFMM:
Superman is back open, but only the backwards side. An employee working there claimed the forward side won't be opening anytime soon.
Membership signage is also down at the old Membership/Season Pass office in the plaza area (the area between MM and HH).
They are also now trying "Front Gate" parking... for $40 at the parking gate, you can park in the first row, no reservations needed. Not sure how long it'll last, though... an employee said they've been doing it for about a week and a half, and the most he'd seen were 7 cars using it.
On a side note, nothing is still vertical on the new Wonder Woman ride site. Just footers and flat dirt. They did remove the Wonder Woman signage from the flat ride, but the ride itself is still there.
