Pros:
So many. Multiple spacious, cement teepads on every hole. Baskets with multiple positions that actually make a significant difference in both the layout and the difficulty of the hole, and which are rotated pretty regularly. The course is laid out on a hillside that a about a third of the holes go either up or down. So lot's of elevation changes, but it's the same slope. Hole 11 (I believe) does go down a different and steeper hill, and is wide-open- it's a lot of fun to hurl discs down. Good variety of wooded and open holes, and the usually noob-unfriendly hole 3 has you throwing right over a densely-overgrown creek.
Cons:
CROWDED with a lot of casual and serious frolfers who are occasionally prone to getting irritated with each others. No individual hole is hugely memorable.
Other Thoughts:
This is a really solid course without a doubt. All of the pros I listed are totally valid, but what really makes Seymour are the people who play there. It's true that there are lots of people in Omaha who consider it their home-base, so if you like a brisk, quiet, concentrated round you might get irritated by people playing music, or stalling you up with a large, unskilled group. But I hear enough quibbling about the lack of etiquette that I want to point out the overwhelming sense of cmmunity and goodwill that almost everyone brings there. People are just chill and friendly, happy to chat or let you mind your own business if you prefer. If you are playing by yourself, most groups will let you play through. There is a notable lack of litter around. People are know to bring drinkables, but you wouldn't know it from cans and bottles scattered around the course, just by the heaps in every trash can. Here's an example: Earlier this summer, I found a frisbee with a name and number on it that I called to see if the owner was still at the park. He was a few holes behind us, on his second round of the day, and we agreed to wait for him at the picnic table after hole 9. When he arrived, he gratefully took his disc back and recognized the friend I had been throwing with from a wallet that he had found some holes back.My friend had dropped his wallet without even realizing it, and this individual, whose frisbee I had just returned, returned it to him without being prompted. That is the sort of awesomeness that is cultivated at Seymour Smith. Also, the course is legitimately pretty boss by its own merits.
