Personally, I havent ridden ST. Louis. I guess I should go try it out, if the park is any good??
As flat as ON is, we have quite a few pros coming out of Ontario. Lots of great park riders. Sure it's not Fernie or Whistler, but the Ontario boys can sure throw down!
Yup, try MSLM. It's only 10-15 minutes farther along the 400 than Horseshoe, and has two terrain parks and two half pipes. Sadly, the Outback (the good parks) might be closed for the season as we're quickly melting away. Lots of really nice features in there.
Parks are one of the few things a small resort can try to do well, since they don't have the vertical for good alpine. Don't need a lot of vertical for a terrain park (unless you want a massive X-Games slopestyle run), and can put a few of them throughout a resort to space out the people. Ontario gots to represent in something eh?
