Thats the resort I learned at, I grew up in Hill City, SD.
It's a fun little mountain, gets the job done. They recently replaced the red chair with a new high speed quad and have plans on adding another lift and more land in the next five years. The preseason season pass is around 300 bucks.
The Park is hit and miss - Some years they have a good jump line and a half pipe, other years it's just a couple 20 footers and rails/boxes everywhere. Hopefully they step their game up there - It would really help the resort IMO.
There are some fun little tree runs to keep you entertained. About a 5 hour drive to Denver..
