The whole thing backwards, or just the inner loop?
Whole thing. I took different routes 20-19, 18-17, 15-14, 14-13, and 4-3 than the opposites.
I guess this one is like that old Boy Scout joke about underwear. You can wear it four ways: regular (17:30), backwards (17:25), inside-out, and inside-out backwards.
I'll have to fill in times for the other two soon. I guess that would be forward with a backward loop, and backward with a forward loop?
