Earlier I decided to explore pale pass, which I remembered from Oblivion and was marked on the map with Skyrim. Anyway I ended up seeing how far south I could go and arrived at a camp far above Falkreath in the mountains. Here I met Angi who had a shooting range set up outside her home. She had lived here for a few years since her parents were killed in Helgen by drunken Imperials (who she later killed in revenge).
She said I could practice with her and I agreed so she gave me a series of challenges (hitting targets in a certain time etc) which upon completion raise the archery skill. I just got 6 skill points for free :D
It was such a remote place I didn't expect anything to be up there but turns out I was wrong. I love Skyrim's attention to detail, its the little things like this that make the world so great. Anyway have you come across Angi? What other small details have you found?
