I hope your rig has quality tires and good suspension. The roads in Umtanum are miserable! Among the worst in the state IMO. I have taken a spike and a cow in there in the last 5 years. If you find elk prior to opening day make sure you are the first one there on opening morning. You will have company. It's no thing for guys to park next to your rig and walk right in on top of you. Good luck, have fun!
