Going up to Observatory from Mines was great...not too bad at all.
Coming back down from Observatory to Mines was a different story...3-4x much gravel..all I heard most the way down till you get back into the Upper San Antonio Valley/Ivy Canyon was ding ding bing ding bing bing ding
I had about 3 pieces fly up and hit windshield..so yeah stuff going everywhere
Hopefully within the next month since weather is better more people will fling the gravel off the road
