Safety Cones - Do you carry them?

I carry a pop-up cone. Can't remember where I purchased it, I think in Quartsite many years ago. Seldom used it. However, on the way back from an Oregon Rally I saw a fellow rallyer needing roadside service. I stopped, all was well, but I left him with one of our cones. I also keep a couple of collapsible triangles in the coach. I think a full size cone would take up too much room in the rig.
