Two additional observations on this: 1. I did not see (and rightfully so) a single comment blaming the equestrian for being on the road, and I sincerely doubt that I could say that if a cyclist were on the receiving end; we all know how the creeps and blame-the-victim types come out of the woodwork when a cyclist is hit. 2. Some journalists still report this sort of thing as an "accident".
Well, I didn't originally intend for this post to bring you down, because otherwise it was a great morning up there. Clear, cool and, I had my climbing legs. Here's a pic:
A lot of Lupine in bloom, even more Monkey Flower (though I didn't stop for a photo of it). These Lupine were growing on the other side of a low stone barrier wall, you pass coming back down; it is about the last place you have a view down into San Gabriel Canyon before you cross over to the other side of the ridge.
