I find it odd, and maybe it's more for the how the story was meant to play out, but surely once Harry knew his parents did not die in a car crash he would want to visit their graves? Not once in the 6 books before Deathly Hallows did he ask anyone about where they were laid to rest. Not even Hagrid after he gave Harry the photo album, not Sirius/Lupin/Weasleys/Dumbledore. Even if they had died in an accident surely there would be some burial place for them, although somehow I don't think the Dursley's would have let him visit. Is
Is there anything in canon/interviews that explain this and does anyone else find it strange?
