I live in Michigan - plumbing supply folks say they don't carry ABS because plumbing code in this state does not require it...can be special-ordered, but that would mean a full box or other minimum amount.
Apparently Indiana uses it. An architect in town here said I might be able to find other users in-state, like maybe roof or landscape drainage, but he started thinking concrete was more likely, or with holes. Those of you who have sources...how large a diameter have you seen, and what about caps? I saw a 16x20 Unicolor tube in an unopened box today for $75 but a roof leak and possibly photo chemicals had gottenteh box wet. It wasn't a particularly great deal so I didn't 'need' it.
