Climbing in Teutonia

After moving to Germany I was initially a little disappointed with the climbing potential around Bielefeld. It's kinda flat here. Nice forests but very little rock potential. Until last week I had a quick look at the Halleluja Steinbruch. It' a damp, wet, low old quarry but at least there is some real sandstone rock to climb. From the pics it seems there is even some 'winter' climbing. There's always the indoor climbing place Speicher which looks nice albeit a little claustrophobic.
