At one point, the courtyard in Winterhold had 4 dragon skeletons in it. You could barely walk across it. A dragon spawned in Riverwood early on and before I could bring it down, it killed half the population, who have never been replaced. Same with Morthal.
At one point midway through, an NPC gave me a dungeon fetch quest. I fast-traveled to the dungeon, and had to kill a dragon. Then I went in the dungeon, got the item, and came out. There was another dragon. Killed it. Then I fast-traveled to the NPC's location and guess what? 2 dragons.
It's getting to the point where, even though there are lots of quests left to do, I'm so [censored] sick of killing dragons that I've almost lost interest in playing. Does anyone know if there is EVER a way to get them to spawn less? (I'm playing the 360 version, BTW.)
