step one. find elk habitat in the areas you have a tag for.
step two. start hunting elk.
sorry to sound like a dip but its really easier then people think. elk and deer are all over. you just have to find them. your first year or 2 is probably not going to be very successful, but thats hunting.
odfw has harvest reports you can look at. i would also pay attention to the travel management stuff. some roads are open all year round. some roads close in august. some roads are never open and as far as i know its up to the you to know what roads are open and closed at what time.
