Narrative:

Called ground for taxi. They told me to taxi to runway 18R at M6. I read the clearance back and taxied to runway 18R at M6. Called tower when I was ready. Tower cleared me for takeoff runway 18R at M6. I read the clearance back and took off. I heard nothing more from tower. 2 days later, company called me and said someone had called them and said I took off on a closed runway, but they had reviewed tapes and I was cleared for takeoff on that runway. There were no barricades or flashing lights, and no signs indicating it was closed at that time. I think any one of these things might have stopped this situation from happening.
