When I worked the Wings Over Houston show in 2003, I noticed that they had
a very effective portable signage system. This consisted of a series of
folding "sandwich-board" type signs made from 1/2-sheets of plywood, OSB,
etc. hinged at the top, with a short section of rope attached to the backs
to keep the signs from spreading open too far.


We're lucky, we have an old trailer for all of our signs.

We use 50-70 lb sandbags under each sign:
1.) Wrap a short bungee cord around the sandbag.
2.) Hook a couple of bungees, from the top of the sign, down to the sandbag
bungee. Easy and quick ...and cheap.

Good point on the spinning arrows! More people need to do that when creating
signs.
