Hints to find
51 items on Route 66
Read this only if you can't find any item for more than 20 minutes
Murlocs
Three murlocs are next to each other. The other two are pretty close
Rusty buckets
Are you sure that there is only one bucket in this tunnel?
Cassidy photos
It's hard to see the last photo. Especially if you have already found several items next to it. But you can definitely see the weapon next to the pic.
Just check all places similar to those where you already found one of the photos.
