Large diameter corrugated pipe?

[mullannix930]

I'm trying to get some attractions addad to Greenbo Lake. One I thought about is the corrugated culvert pipe. Does anyone know where you can get some (36" or 48")? Since Greenbo is done by volunteers and donations, the cheaper the better.

You might call Pennyroyal & see where they got theirs.... Just a thought.
