Oh yeah we have a LOT of bombs still buried. They are being defused whenever we find one. A few months ago one was found a few streets from my student dorm. There's always a big evacuation, but as far as I remember they were always able to defuse it safely so far.
And yeah, I never heard of inside skating. We usually do it outside. And I'm pretty good at covering distances with inline skates, not so much at doing tricks and stunts. And ice skating is just like inline skating, except you're doing it on ice. I can do it, but I prefer inline skating.
