Summer holidays! We took the chance and our old-fashioned bicycles to bike the former military training area near Münsingen. 2005 is was shut down and turned into the biosphere area Swabian Alb. We climbed the abandonded observation towers, made rest at the former village of Gruorn and took another break at the Biosphere Center. Exhausted, but happy, we made it back home after roughly 7,5 hours and 31 kilometers - just in time for a huge sundae!
