Polson is rad. The bowl snakes around from a mellow 3 feet deep to about 8 feet with fun hips of all shapes along the way, with a spine between both sections, then there is the door... A door. Super fun to grind over. That door leads you into the deep vert section, then there is the HELMET...a freakin' Helmet.
The street stuff is also super good. There is a pyramid bank that alone could be skated all day. Ledges, stairs, Large gap steps, you name it. Polson is rad.
Another good aspect of Polson is that it sits right on the South shore of Flathead Lake (largest freshwater lake west of the Missippi and one of the cleanest of it's size in the world) which means it get really mild weather due to the massive body of water next to it. This means that it will be skateable way earlier than other parks after winter and in the summer you can go jump in the lake and cool off. The town is also an hour north of Missoula, an hour south of Whitefish.
