Hitting a wall

I was jogging with My Diesel today around Greenlake. We'd just started up again after a little walk spot and I'd just hit a really nice stride when BAM!! he crossed right in front of me! Everything went slo-mo for a second as I felt my knees hit his rib cage one at a time, we looked into each others' eyes on the way down, I saw his arm come under him and he landed on his left shoulder and the next thing I knew, I was on top of him on my stomach. I'd have a bloody chin if I hadn't landed on him. He was up as soon as I rolled off of him, making sure I was OK. As it is, my hands are a little banged up and I may need to have my spine cranked back into place one of these days.
