I really loved discovering the Daedric Shrines. And then doing the Daedric Quests. And when it came to mods, I loved the Unique Landscapes. I was yzerman19 of UL fame...so of course I loved it!
Here in Southern Arizona, we love it whenever it rains, because it rarely does. Besides, the way my room is arranged, I am far from the window, and I keep the blinds shut 24/7...so it does not matter.
I also enjoyed Vilverin back in Oblivion. Did not go there all the time, though. And the innaugural playing of Skyrim, I will probably go check out Riften, and get my bearings.
