In reply to KieranSQ:
I've run through the Polish Tatra and we came across a few sections of chains there. Only looked down into Slovakia, didn't actually cross the border. I found the chains useful, more for coming down quickly, than ascending. I'll try to send you a photo or two. No special gear was needed, just a bit of a head for heights. As previous post says, loads of locals were on the hills in Poland and they all seemed to cope so the chains are well used and fairly 'normal', not difficult or particularly dangerous.
Have fun....
