First work order this morning at 5:40 am... quick change-out of a clogged Toro 300 Stream Rotor nozzle at a junior high school next door to our shop. Dig a little around the sprinkler to better expose the head and put hands down while kneeling on sidewalk. Within seconds I'm covered with damn red/black ants we call piss-ants. Got bit six times on the left hand before I could shake them all off killing as many as I could. Welts all over! So I change the nozzle, break out the primer and start stinging back. Gawd damn piss-ants!
