I saw the incident. Sell was about 10 yards behind the lead pack of Carlson, Browne, Bizuneh and Coolesat. The branch that hit him was bigger around than my leg and was about 8 feet long (no exageration). I thought that it knocked him out when it first hit him. 2 guys ran out from the curb to remove the branch because it took up a good portion of the road. It was wicked windy that whole section from 3 to 4 miles along the water. The waves were hitting hard against the seawall and splashing over the road.
