Mine is on straight. In fact mine was placed correctly - I have seen to many mounted too high up and not below the bend where it should be. I took it off and put some plugs in to get some estimates when I bought it to fill in the holes and paint them... After two estimates, (about a week with plugs) I got pulled over for no front plate...
In texas I believe you can stick them in the front window (I think it states it has to be able to be seen from the front of the vechile - not attached to the front, but not postive). The problem is that as curved as our windshield is, it does not work well and may scratch something.
I still think I may yank it off again and fabricate a way for it to attach to the passanger visor, that way i can just flip it down when passing throught the pickey counties and have it look normal for show.
