Almost a week after "finishing" this game I'm still thinking about it constantly, so I decided to go back and try to clear all shrines. Did all the shrine quests I had remaining on my quest log and re-checked any suspicious places I remember not finishing up at. Still only have 102 shrines and I've already been all over the world. Don't even know where to start looking.
Guess it's time to turn on the shrine sensor and wander aimlessly.
Do what I did and find a map of all the shrines on the internet and go from there.
I spent way too long wandering around with the senor and it not paying off.
