Revisited the SL&C area for more practice climbing the slippery slope. Made seven ascents from the Y at the bottom of the loop. Kept losing traction in a particular spot where I'd veer right in a vain attempt to put my tires on a couple of large rocks; islands of grip in a gravel sea. What I discovered on the seventh run was that there's a tiny strip of decent traction on the righthand edge. D'oh!
