Signs and billboards are all over the map in this area. I presume that you
have read through the ASCE 7-95 Commentary, Section 6.6, Category III.
Probably no one has tested more billboards than Cermak, Paterka, & Peterson
in Fort Collins, CO. I would give them a call.
By the way, I have not received it yet, but ASCE 7-98 is now available.
