I wish I lived closer, because that pipe looks very interesting to me.
I have met: Tom, Steven (bouaboua) and his wife, Irene, Robert (Got turtles), Murray (68merc), Clem, Darlene (Ladyrags), Penny, Will...I hope I'm not forgetting anyone. Senility has set in.
Go up to any commercial construction site near you where they are still doing the dirt work and ask them for a scrap piece of corrugated storm pipe. 99% of people will happily give it away so it doesn't take up space in their dumpster. If not I can always ship you a piece.
