So I don't know what I did but I completely uninstalled Adobe Reader. So whenver I went to see a PDF on Safari it didn't work and it was frustrating. So I went to Adobe Reader and downloaded it (for free of course) and now I see the Adobe Reader in my Apps. When I go to open PDF's in Safari it now works. But I don't remember seeing the Adobe Reader App before so now I'm starting to wonder if it was already somehow included as a plugin with Safari and I messed it up. Now I have the Adobe Reader App installed and it works in Safari...but did I need the whole App to look at PDF's in Safari?
