It's back … the legendary Big Nasty Mud Bog, slated for 6 p.m. Saturday, right after the X-Climb. Come and watch the slimy chaos at the Big Nasty Ditch between the pits and the campground. Or enter here. 

The side-by-side hillclimb is scheduled for Saturday evening. The four-wheeler classes are earlier in the day.

Idaho's best country and classic rock is coming to Big Nasty Land this year with a great stage up front featuring headliner Pilot ErrorSimple Ruckus, the Grant Webb BandDusty and the Claim Jumpers and Rodie & the Big Nasty Band. The event will also be bringing in both an adult and kids water slide and an escape room.

World jump record holder (425 feet) Alex Harvill will be signing autographs at this year's Nasty and competing in the Pro hillclimb and looking at the lay of the land to see if he can set a new world jumping record at next year's Nasty.
