I’m in Berlin for a few days, staying with my future sister-in-law and enjoying the lazy summer days spent at Pride parties and giant airport parks. Yes, airport parks. Berlin used to have an airport called Tempelhof, but in 2008 it was shut down. Now they stage marathons and festivals here, and it’s been a park since 2010. Lizzie and I spent a Sunday afternoon picnicking and chatting on the grass next to the runway, watching people play. After awhile, we realized we were seeing the biggest variety of things on wheels we’d ever seen before. Rollerblades and bikes, sure, but also kitesurfers, moving ellipticals, and dry land skis. The Berliners love finding new ways to zoom around their parks! Check out the many wheels of Tempelhof.
