Doesnt appear to be a failure as far as concrete depth, the
sign doesnt seem to be that large to me. If it was a straight line wind whats was gonna happen did. We had a billboard taken down by straight line winds in out sity several years ago. I had a
sign in a neighboring town blow over on top of a stone monument. I have 5- 5/8 x 8" titan screw in this
sign and it blew my
sign over and took all the stone with it....meanwhile 8' away was a damn yard sale
sign still standing. the
sign was 36" x 10'
