For my billboard I chose to use the Riverview billboard that is out on hyw 54 coming in to Rapids. It was the most detailed I could see from that side of the road.
I believe that ad spending has increased on outdoor spaces because more and more people are on the go. With jobs being on the decline most people are finding themselfs having to travel to find jobs. Where are most people duing these times? On the road. So advertisers are taking notice of this and are spending great deals of money to advertise on highways with alot of open area so that you are forced to notice their ad and they are posing where ever else there is space like on buldings, buses, chairs, etc.
