QRHey wow, some proper training, getting reacquainted with the invisible boulders of Tiger - a Thanksgiving tradition. I found 1-4 without too much extraneous searching, spiked 7 nicely, but never saw the boulder at 8. Also didn't discern the point features around 5, but figured I was basically in the right spot. Problems all the way on 13, didn't see the ditch or a notable knoll or anything that looked remotely like a ride, but again, close enough. It's possible that I've run this course before; some parts seemed familiar. Felt pretty slow, but it was nice to get the blood flowing properly for the first time in a while. Lovely fall day, 50s and sunny.
