We just walked into Longyearben (it's a fairly long walk, by the way) when we were in Spitzbergen. It's a nice little town with some nice shops and a post office if you want to send post cards. But even the town isn't without risk there--some of the people walk around with rifles to ward off polar bears that occasionally wander into town. We didn't see a bear, but we did see bear prints on the walk back to the ship. That was just before we were attacked by a demonic sea bird who dived for my head several times--even hit me once with her wing. I assumed at the time that she had a nest nearby where we were walking. Bottom line in Spitzbegen--proceed with caution ;) .
