I also noticed in a couple pics that there appeared to be quite a bit of spilt fuel and not one grain of drysweep visible. Just let it run down the down the curb to the sewer ( or right into the river as it looks like it's on a bridge). It's kind funny, I can still remember when the US Army was that lackadazacle to oil and fuel spills, that is until the EPA started fining the military )
