Honestly, if you didn't put them in first, you're crazy.
Nah man, Walpole's first.
While Walpole is a strong contender, I would have them no higher than third, with BASIS in first and Riverton in second.
Yankton definitely has the potential to earn 4th place as well. Their seasons have just been getting better and better, and they've won states every year for as long as I can remember.
Two years ago I knew stuff about rocks, minerals, experiments, and ecosystems, yay!
Last year I knew stuff about amphibians, reptiles, water, and more experiments, yay again!
Now I'm learning stuff about oceanography, fossils, and writing/following instructions, yay for the third time!
