Where are the Billboards?

3. Billboards
Only four states — Vermont, Alaska, Hawaii, and Maine — have outlawed billboards, and Hawaii’s ban has been on the books the longest. You may not realize this small perk while stuck in Honolulu, the nation’s second-worst traffic city, but you will notice that many of the state’s roadside views are uncluttered and gorgeous — a testament to how much the Aloha state values its ʻaina (land) and preserving its beauty.
