Where did the sunshine come from? It must have been fleeting. When I was cruising for pix last weekend I noticed a fire department crew hanging out by the Mississippi. That boat looked too small to be a pumper for marine fires (which do happen - STL is a large inland port for barge traffic. Note the line of them in the background.). It was clearly the city fire department. Anyway, my guess is that this was an emergency rescue team on a training exercise.
