Making your disc golf course unique

Clearly hole design is the easiest way to make your disc golf course unique.  But what else can you do to really make your disc golf course memorable, fun, and challenging? 

Some things I've seen -

- interesting barriers/obstacles (farm equipment, hay bails, boulders)
- raised and sunken baskets
- gravel fairways, woodchip greens
- big, informative, eye-catching signs

give me your two cents.

I love that hole!

Rock walls that tier elevation changes. I've seen many rock piles and towers but I want each hole to really be its own piece of art with landscape structures defining each fairway and/or putting surface/area. I rarely see that in courses.

I'm voting for a banjo playing monkey on a swing with dancing clowns.

I always liked the bowling ball lined fairway at chili (pronounced shy lie) in Rochester. There are also 2 pretty good sized silos, and some kind of fake paper mache looking trees.

Boring yes, but stick with the natural beauty of a course and use it. All I have to say is "Top of the world" and most people will know what it means. I just don't think you need gimmicks to make a hole challenging, beside, once the novelty wears off. Most people will forget it. If you don't have much to work with. Go with Eiriks post. With the use of O.B.s and "bunkers" (PDGA style).
It's the natural holes (for lack of a better term) that I remember. Not the ones with windmills and dancing monkeys.

Dancing clowns damnit.

I agree that the holes that I remember are the ones that have some sort of natural feature that makes them stick out in your mind. Hole #18 at Sipapu where you have worked your way all of the way to the top of the mountain and then you throw straight down 800 feet. I'm sure there are some great water holes as well out there. I'm not a big fan of artificially creating something weird or unusual. Generally great holes speak for themselves.
