I expect I will busy myself with seeing about all manner of travel to various and sundry museums and monuments, including museums of art, monuments to old and venerable times of monarchy, and remnants of a great and storied national history.
Something to consider about the city is its cleanliness and its modernity: There is no heavy industry and not a single fossil-fuel power facility in the city or its metropolitan area. It is famed for its modern architecture and low-key planning: very few buildings in the entire city are higher than two stories. Following Scandinavian architectural tradition, the roads, sidewalks, causeways, driveways, and buildings are spaced generously apart from one another, allowing for a broad and liberating feel.
Yes, there is a lively and considerable nightlife- but I seriously doubt I will have much of anything to do with it. Not much my cup of tea really, but when in Sweden...
Were an enterprising international student to feel the transcendental call of the natural wilderness as did Thoreau at Walden, he could simply travel just outside the city to be greeted with an absolute wealth of forests, endless lakes, streams, and hundreds of islands.
The charming and varied villages throughout the hinterlands of County Stockholm could prove well worth the visit- one never knows what he might find.
Something I'm downright excited about is the sheer number of gyms and health clubs in Stockholm. There are dozens and dozens of them. I'll have to pay more than a few a visit.
I suspect I'll have no shortage of things to do and see, places to go, and experiences to be had in this frosty far-flung city.
