Hints are great, but be wary of making it too obvious what's going to happen in your novel.
If you've ever watched a TV show or movie and heard a random stranger say something like, "Well now, we haven't use that road since a big old sinkhole opened up ten years ago," you've stumbled upon a telegraphed clue. You know that sinkhole is totally where the hero is going to lead the horrible monster or bad guy chasing him at the climax—and he does.
Kinda takes all the fun out of it, right?
