In reply to wbo:
Yes I have bolting routes in mind. I can get hold of a bolt gun quite easily. I've only been living in Oslo since May. Don't really feel I have a lie of the land sufficiently quite yet. Need to keep exploring and for a little while I think. In the short-term it's good to start where there are existing routes. Maybe these crags can be developed...
No, don't really think there is any real development in Norway so this post was more of a long shot. No real ethics concensus surrounding dry tooling either so want to set a good precedence.
Most of the quarries I've seen don't look friendly places for climbing and it doesn't seen 'normal' to climb in quarries in Norway. I imagine there could be problems! Also, I think the local residents association will have issues with me using the kids playground outside more flat for practice
