The 2 Things Challenge for this week is Push / Pull.
My entry is a tug boat that met our cruise ship in Guatemala. Modern cruise ships are so maneuverable with their side thrusters and all that they seldom actually need a tug. Depending on how it is helping, tug boats can both Push (note all the tires) and Pull (note the heavy rope). This one actually did nothing except ride along side the cruise ship and look colorful.
