I came out last fall to find the "Sunfloweres are us" cache and fell in love with this nice pond with several islands. I just had to place a bunch of caches on it. The caches shouldn't be very hard to find if you follow the hints.
You'll be looking for colorful bison tubes which are all hanging around somewhere. You're going to be needing a boat to get them unless you want to wait until winter when you can walk on (frozen) water. You will have to get out of your boat to get at least one cache. Have fun.
