Those are tough ones. Sometimes you just have to take a break and come at it with a fresh perspective. Try not to do too much landscaping, I don't think course designers like it too much. I like to hunt for a lost disc with the sun directly overhead b/c when it's throwing shadows every where it can be a royal pain.
Oh, and if anybody found an uninked blue Eagle-L with "high times" dyed on it, graffiti style at UNC, hook a brother up.
