Basically what the title says,

I'm looking for a Dean/Sam fic, semi-long (20k-ish, far as I recall), fluff/post-apocalypse. They're going on a roadtrip to see things, I think they go to Disneyland or the Grand Canyon? And they talk about donkeys and eat peaches or strawberries in the impala. It's first time/not established.

It's probably old since I read it in 2013-14.

Not a lot to go on, I know. Thanks in advance!
