Pros:
-Fully dedicated course right on edge of campus. Never crowded but never empty either, good safari opportunities.
-Good mix of trees and prarie grasses throughout.
-Holes #1 and #9 feature nice elevation. #1 is a 400 ft+ basket you can actually throw for given a 100+ foot drop from the tee. One of highest elevated tees I've seen anywhere.
-Most holes require strong accuracy or involve a dog-leg to the basket. On holes #2 and #3 you will be fortunate to thread the needle through the trees.
-Hole #5 is a "narrow fairway" between thick forest and thick prairie. Disc loss / searches very possible although better players can probably nearly throw over prairie to basket.
-Very laid back and ultra quiet right on the edge of civilization. You will only see other disc golfers, mainly college students, and a few random locals.
Cons:
-Nothing's marked, so be prepared for a few moments of confusion. There are a few alternate "official" versions of holes, depending on who you talk to.
-First timers may need a little back and forth to transition in and out of Hole #4. Because of tree growth, etc, over the years, the progression from hole #4 to #5 is no longer very intuitive, so be prepared. You actually walk all the way back to the #4 tee area and then continue towards Highway 19 for tee #5.
-Holes #6-#8 are super shady and can get muddy / buggy if there's been any recent rain.
-If you're playing in the evening be sure to bring bugspray. Like Raid Yard Guard. Forested areas near hole 2 and hole 6-8 are notorious.
Other Thoughts:
I've been playing this course on and off since the late 1990's. The trees are taller and the baskets are starting to rust but the overall feel and enjoyment factor hasn't changed. Carleton has a solid 9-holes as well, put in around 2000, with overall more challenging longer holes smattered along the edge of campus. If you only have time to play one I'd go with Olaf.
