Just for fun, I tried to figure out how many loops you could have from the first tee at Idle Hour that comprise between 4 and 8 holes.
1 - 6
1, 2, 3, 4, 5, 18
1, 2, 3, 8, 9
1, 2, 3, 4, 5, 6, 9
1, 2, 3, 8, 17, 18
1, 2, 3, 8, 7, 4, 5, 6, 9
1, 2, 3, 8, 7, 4, 5, 18
1, 2, 3, 8, 9, 10, 11, 12
1, 2, 3, 8, 9, 13 (9-13 transition might be a touch over 100 yards, but it's straight through the parking lot)
1, 2, 6, 7, 8, 9
1, 2, 6, 7, 4, 5, 18
1, 18, 10, 16, 17, 6
1, 18, 10, 11, 12
1, 18, 10, 11, 15, 16
1, 18, 10, 11, 15, 16, 17, 6
1, 18, 13, 14, 15, 18
1, 18, 13, 14, 12
1, 16, 17, 2, 6, 9
1, 16, 17, 2, 3, 8, 9
1, 16, 17, 2, 3, 4, 5, 18
1, 16, 7, 8, 9
1, 16, 7, 4, 5, 18
1, 16, 7, 4, 5, 6, 17, 18
1, 16, 7, 4, 5, 6, 9
1, 16, 9, 13, 14, 12
1, 16, 9, 10, 11, 12
1, 16, 9, 13, 14, 15, 18
I stopped at 27 because my head was starting to hurt. Again though, that's only counting loops starting on 1 (and I didn't count all of them). You can also start on 13, 10, or (if you spend some time practicing your short game first) 11. From the rear parking lot, you could also start on 9, 17, or 7. I've never seen a course routed anything like it.
