We had concert tickets on Sunday—we went to Bonn to see Billy Idol, with New Model Army as the opening act...
The whole thing started at 6:15 p.m., and we stood “front of stage” for about 4 hours.
That was pretty tough in the heat, but luckily we were in the shade of the stage right from the start.
Afterward, we walked about 3.5 km along the Rhine promenade back to the hotel; the air was much cooler there, and after the crowds, we were able to catch our breath a bit and enjoy the beautiful sky.
