RE. Okeechobee Painting error
Per WHBM:
No alligators ? 
Per KT550: I don't remember seeing mountains at the real one
Per YVR Cockroach:
Indeed. Pretty much having never been very far north of I-4, I always thought overpass embankments were the highest topographic features in Florida. Shockingly, there does seem to be terrain above 200' ASL in the vicinity of Ocala.
Per jrl767: I’ve never been there, but knowing the general topography I totally agree that the hills look ... well ... less than realistic
And the mountains have it! While they do add some nice contrast to the picture, the highest mountain in Florida is probably Magic Mountain at Disney World
