Alexanderplatz, Berlin. Berliners are serious about their wurst (sausages): they're available in ten or fifteen different forms on a regular basis. This gentleman comes complete with propane(? some kind of fuel) tank on his back, grill supported from the backpack by an iron bar between his legs, and an umbrella: he is a mobile unit. Although I shudder to think of the weight, especially at the beginning of the day when the fuel tank is full and he has all the buns and sausages. There were at least two other similarly equiped vendors wandering Alexanderplatz at 4:00 in the afternoon, and another in a wheelchair.
