Need help building Speedball field

[Ziegler42]

Hey im building a speedball course right now and I can't figure out what those tubes are they use. If anyone can help it would be much appreciated. Please post where i can find them and how much.:D

I suppose you mean the black tubes they use in hyperball fields. Thos are corrugated polyethelene pipes. They are very expensive. A 24 foot long 18 inch diameter would cost probably about 160 dollars. Im making a field out of those except instead of buying them, im getting them from contruction sites in my town. Ill post a pic of them later.
