The Park Madness FINAL FOUR are set. Yellowstone won the Mid West region with a blanket defense that didn't run out of steam as Glacier had hoped.
Down South Everglades out battled Great Smoky's with hot shooting from the perimeter and stifling defense that left the Smoky's wilting under the heat.
Up East the Washington Monument made three late runs and closed the gap, but Gettysburg's defense held out, especially in the middle where the Washington Monument thought them most weak.
Finally in a stunner out West, Denali's massive presence in the middle of the court shut down Yosemite all but certain climb to the finals.
