i live in minnesota and usually go to mountkato. it's a typical midwest spot with no elevation, but has pretty decent park features. i'll also hit up afton alps near minneapolis a couple times a month.
other than that i'm checking priceline for cheap flights to denver, tahoe and slc, and try to head out there at least once a month.
I live in Chi town, so i'm stuck with some pretty crappy mountain options as well. I would say for longer runs (and i mean like a total of 8-10 minutes if you're going through it at a medium pace), you should hit up Devil's head. I also found this resort to be generally empty so hardly any lines. Another spot that I usually hit is Cascade Mts. They usually throw in a bunch of random jumps and rails throughout their runs.
