A now closed grass strip in Odense, Denmark. 695 meters - not that impressive.
Made touch and goes. Had about 20 hrs, rain and 15 kts crosswind. On one of the T/Gs almost made an overrun into a fence. Sunk into a pool of mud - no room for stopping - so got airboune with about 45 kts, speed building up very slowly in ground effect and 10 cm over the 2 meters fence!
