Hey all! I made you a thing...

I strongly urge you to read my recommendations for Validator checkbox selection for maximum benefit. If you edit in more than one State, please remember to toggle this script OFF when outside Iowa, or every road will show up as an error there due to having a non-Iowa State.

If you have any other checks you'd like added, I'm quite happy to do so!
