Rick, didn't see that guy. But right after you left as I got about 1/4 mile in, I came across a couple walking up the wrong way. At first I got kinda peeved because you know I had to slow down.....but as I got closer I could tell something was wrong, the young man was helping the young lady walk. I asked if they needed help and he said yes. It turns out that she fell and cracked her head pretty good. I helped him walk her out and called 911. I took a look at her helmet and the inner lining was cracked. Thank goodness she was wearing it, she was in very rough shape on the walk out. I really hope she's ok. Fire/ems arrived and took care of her. It reminded me of how careful we need to be while enjoying the trails. A slight lack of concentration and be very dangerous.
