Hmm...trying to decide whether to have garudas or dragons in my YA fantasy novel. They'd be serving a similar function either way -- large flying beasties for my characters to ride into battle. It's a Sri Lankan-ish setting, but I can make a good argument for dragons showing up too, one that makes sense within the context of the book.
I do (rather madly) love dragons. And I just saw How to Train Your Dragon on Jed's recommendation, and loved it, and am feeling even more fond of dragons at the moment as a result. But there's a case for sticking to cultural coherence too. Hmm....preference? Which would you rather read?
