Annie, quad city,Iowa. It is a garden show I think it start's on the 23rd. I am not positive where the show is held there my guess is a convention center maybe. I tink if you google quad city flower show it migt say.
And they are temporary. Most clients take tem down as soon as the event is over but some have kept them up and let nature take it's coarse. The longest outdoor one to date was just over a year. It went through several snow storms and a spring thaw.
CorsairMac-the AZ fair if I am correct was 1994 and 95. Tough jobs too. 8 guys 1 women (me) and 115 degree weather for 32 days. I only broke down and cried twice on the first one and once on the 2nd job. We got 4 inches of rain in two hours on the 2nd job. Erased two weeks of detail. I cried as i watched it go away and then started laughing. grabbed a piece if plywood and started surfing the run off!
