This from the Chamber office in Salem.....might work for you.
Also, we have an off-road park that has a brand-new house that they rent - don’t quote me but I think $100.00 per night. The reason I am mentioning this is because they just opened, and this wasn’t previously available. “Flat Nasty Off-Road Park” 573-729-6668.
It's about 15 miles South and west of Salem...They help us with our sweep vehicles and our sweeps are having a jamboree of some kind there Sunday after the Rally.
