Since Tom (and others) mentioned 4 hole loops, I'll put 10-11-17-18 at White Bear YC as a great example. Play a round, enjoy a beer (or 2!), then play the Loop (as it's known). Par 4,3,3,4 and great fun. I have to also mention a 2 hole "loop". When visiting Prairie Dunes with my sons and staying on the property, we played 8-9 a couple of times after dinner. Fab.
