The College of Winterhold is a pretty awesome place to fight a dragon as the archmage.
If you go to the top of the archmage tower, it's like an epic mage's duel versus a dragon.
Riverwood is kind of a pain for dragons too.
I like selling stuff to Alvor, but I had to keep reloading whenever he would go kamikaze melee with his iron warhammer wearing blacksmith clothing against ancient dragons by himself...
Yea, even fighting the dragon in the courtyard of the colleges is pretty cool. All those mages hurling their spells at the dragon, and there's no where to go for him really hahaha
That's where I fought my very first Elder Dragon, on my very first character.
Oh I don't even fast travel to Riverwood anymore. I fast travel to a nearby mine and then ride Shadowmere into town. I lost a few good friends there during a dragon attack, now I don't want to risk it anymore on my new character. LOL
