I'll be in Stockholm this weekend and I'll stay there for at least a couple of weeks, so if anyone's in the area and wants to meet up, let me know. I'd also be willing to travel up to an hour or two by train in any direction. I've visited several towns around Stockholm in the past, my favorite being Örebro. I mean seriously:
Second favorite would probably be Uppsala.
I've also been to Gävle and Västerås.
Some day, I want to make it to the far north, but for now I'll be sticking near the capital.
