I agree, if 2020 was the year for the water park expansion we would have to see ground work begin in the back of the park fairly soon. Building a levee and the increase in ground height for the parking lot would involve a lot of earth moving that would take many months to complete. And Minnesota winters cut out Nov-March for most ground projects (think road construction). So they would have to have the new levee built and the roads/parking lot poured by October.
At this point I think a quiet 2020 and the beginning of construction on a coaster for 2021 in the dinos spot would be favored in Vegas. Seems like the army corp project has lost its life..
I still like the idea of an RMC Raptor in the old spot stretching from Riptide's old location to the midway stage. Capacity still seems sketchy with those, but if its working at Great America it would work at Valleyfair.
A Talon or Patriot sized invert also fits nice in the dinos spot. Dive coaster, wing coaster, Mack coasters seem to be more interesting lately. So many directions the park could go in ending our 12 year coaster drought!
Can't wait for the letdown, haha! (Not complaining, I understand it's a business..don't bother with the whiny Valleyfair home park B.S.
