corrugated, but don't worry, we knew what you meant!!!
Does it get hot under there at all with that plastic stuff shazzer?
Brian got several sheets of the old polycarbonate opaque stuff from my work, and I keep getting ideas of what to do with it, but our runs are so big, you couldn't roof any of it, but I was wondering about if Brian made them a verandah thingy for when it rains!
