Went there and found the course. Pole holes are not permanent, but nice mats to tee off from. We were there on a very busy weekend and had to play around two wedding parties and numerous picnickers and campers. Fun little course.
No I don't believe they do. They do have a horse shoe pit.
No, there are not, as of yet.
I haven't seen any but I haven't been there in a couple years, there might be by now. I know there's a disc golf course at the college in LG / La Grande, Google disc golf course around the area should be able to find some 😎
