well I was down there probalby 5 years ago..
Campus is pretty big, with a couple buildings being across the Missouri River which makes for a decent walk. Everywhere else on campus, IMO, is easily accessed from residence halls by foot. I walked most of the way from south to north across campus and it wasn't bad (10-12 blocks maybe? I dont' remember for sure). Parking is miserable from what I gathered (I was dropped off and picked up 2 weeks later when I was done).. I understand it's only upper classes that have the ability to have a car on campus, so weigh that in how you will. However, not having a car isn't THAT bad as right around campus they have what they refer to as 'Dinky Town'. You'll basically find anything you'll need within a few blocks there... Fast Food chains, Coffee shops, laundromats, etc.
Was only in the one residence hall, and it wasn't bad. The majority of campus is deffiently well developed, however the quad-plex of residence halls (there may be more, but there are 4 buildings including a commons area together here) has a nice park in the middle with a basketball court, probably a volleyball court. There are a couple small park areas around the campus, but otherwise it's all concrete.
I personally really liked it, but I also like to have my mobility so being without a car would have been very difficult for me (especially knowing quite a few people around Minneapolis/St Paul). Campus is exponentially larger that the one I'm on now, but it was easy enough to get around...
Snow.. of course it all depends. It'll deffinetly get cold. I can't say personally how much snow sticks around down there (I'm sure they haul a lot out as there's just nowhere to put any).
Deffinite plus about UofM-TC... you're just south of Unniversity (well, Unniversity runs through the north side of campus IIRC), which was known as one of the greatest cruise scenes in the nation (best cruising is from there east for a few miles).
probably grab some more info off of
www.umn.edu Do have a few virtual tours you can check out there.
In my personal opinion...the biggest things I'd consider are:
How do you feel about campus size? Are you against a fairly large campus? (I'm currently on a campus that's maybe 3 blocks wide and 8-10 long... going to UofM-TC would be a HUGE change)
Include in that the campus population.
How do you feel about having a car immediately available to you? Like I say, it'll be tought getting a parking pass if you're new. However you can get most of what you'll need by walking. Not sure how the mas-transit system is down there to put that up as an option.
