Just got back from a week in and around Arizona. I have to say that in that time, I only saw 1 non-political sign in the ROW, and it had been sharked. I can't remember what it was for, though.
Now, if somebody would reign in all the election signs, it would look a lot better. There were usually 20-30 signs in each block that had them, and were mostly the 4'x6' signs that have to be supported by barbed-wire fence stakes.

You are doing a great job out there. Our Governors and Senate races are heating up now here in Texas and I bet we will see too many political signs in all the wrong places. I visited family this past weekend in Waco and found some very large signs along I-35 for one of the Governor candidates. Most cities don't allow anymore than the small "real estate" size signs, but I don't think Waco enforces these larger signs. Keep up the good work.
