Housing your guinea pigs
One of the easiest ways to house your piggy is to use wire cube storage. These are available from many stores; Wal-Mart, Target, etc. They do vary slightly in size, so be sure to pick a size that can be "mated with" later. You can see how to use these in our slideshow. A minimum of 2x2 cube faces should be used.
Coroplast can be used to make clean, durable sleeping quarters, etc. We got ours in Tampa, here. It comes in 4'x8' sheets, so you will have problems getting it into a car, but we just about did it with our old 2005 Toyota Corolla at the time.
Caution! The price of a sheet varies enourmously, depending on whether the sign maker wants to be bothered in dealing with you. Our nearest store wanted $28 a sheet(!). I think we ended up paying about $8 a sheet by shopping around, so we bought four of them.
