There is not much progress going on at the future site of The Joker
The biggest thing that's happened so far is the complete removal of all concrete and other components left over from the former Dragon's Wing sky coaster
Some preliminary ground work has started, and the ride envelope is being cleared of all trees
There are marker flags all over the site
Here you can see some of the side of the hill
These things can come together very quickly, so once they have footers and the base poured, it can pop up basically in a few days. It will be interesting to see when it actually opens this season
