Oh man, those three courses would make for one awesome day of disc golf. I spent the first 5 months of this year in that area and got to play all of those courses, but never in one day. Auburn is definitely my favorite of the three, followed by Condon, then Hanging Oaks.
Condon is very different from all other courses I've played just because of the species of trees. Very different feel in that kind of canopy compared to what I'm used to back in the midwest.
Auburn to me feels a lot like my favorite course, Lincoln Ridge in my hometown (Independence, KY), only less wooded. Flat out enjoyable course.
Hammon Grove is definitely worth a quick visit on the way out. Very well done 9 hole course.
