Just finished reading through the crash report, sorry to hear but glad you're in one piece. The worst crash I had was on Riverside Drive in NYC when I was pacing traffic and at 25mph I hit a large hump in the pavement after which I lost control but had enough sense to make my way curbside, unfortunately there was a large tree there waiting to greet me. Next thing I saw was two cyclists standing over me telling me to stay still until the ambulance arrived. My hospital experience wasn't so pleasant because after a quick evaluation they left me laying on a bed in the hallway; being disoriented and alone isn't that much fun. I had headaches due to the concussion for the rest of the week but eventually all was well.
