Just a tip to everyone who is interested in the S.P.A.D. designs, and others like it- You can get this kind of plastic in 4X8, 4X10, and 4X12' sheets at the local garden supply shop/ landscaping supply co.
Also I get mine (with the blessings of the local police) by tearing off those "lose weight fast", and "we buy houses cheap" signs that are plastered all over the telephone poles. One more place you can get it-dumpster diving at the local cigarette store, lots of temp. display stands are made of this.
