On our ride today we rode through the local park on the bike trail, going down a small hill at a nice clip we kicked up a piece of debris and it passed through the Gates CDX belt and the rear sprocket. We stopped and found that it had actually caused the belt to ride part way off of the sprocket. I carefully turned the crank and it did pop back into position. I would have preferred to have loosened the eccentric but I did not have a long Allen wrench with me. I will add that to the tool kit.

We proceeded out of the park and made a left turn into a subdivision where the road crew had repaired some cracks in the asphalt with that patching material that we refer to as tar snakes, I negotiated them very carefully but still felt a little slip. It seems like they are slicker after a rain when the sun hits them and warms them up.
