Acording to the Minneapolis Star tribune travel section in today's sunday paper Mt. Olympus theme park will be merging with neighboring Treasure Island indoor/outdoor water park. This will be a 80M merger and expansion that will include the addition of Hade's "Extreme underground wooden coaster" and 4 new outdoor water rides. The resulting entity will be named Mt. Olympus water and theme park. (Previously Big Chief's Mt. Olympus.) I was not able to find a link to this info online. But that's what they're sayin' here in MN.
This news is over 6 months old. Not trying to be mean. Just the facts and if you just found them. Your late :)
Check rcdb.com. put HADES in the search and look at the pics :
