So, last night, on my way back from recovering books for the college, a dragon appeared, and swooped INTO the city of Winterhold, and landed in the middle of the college courtyard. I'm sure everyone's seen this before, but this really amazed me for some reason. The fact that a random enemy could come, and land somewhere you've never seen an enemy before (I sure didn't see Daedroth attacking the Mages' Guild in Oblivion) It's just amazing to me. Of course, The College of Winterhold was probably the worst place for him to attack, EVER, but still. Quite amazing. Now his skeleton is a display in the courtyard.
As a side note,

I found the Midden and the Augur VERY cool, also. Something different, and very neat.
