No. That's when I stopped counting. I had many more than that. The wonderful Tribulus terrestris is an invasive plant from Asia that goes every where that the soil is disturbed around from the Great Plains to the West Coast. Probably came here with wheat. It has sharp woody seeds that can lay fallow for up to 50 years waiting for the soil to be disturbed or to be carried away. The nasty little buggers always sit with one spike in the air and the plant can grow to over 8 feet across and bear thousands of seeds. It's very easy to ride across a single patch of them like prathman did and end up with dozen of them in the tire. The damned little things can get through just about anything. Tire liners, kevlar belts, Slime, plastic belts, steel belts, etc will all eventually fail to protect a bicycle tire.

I laugh at broken glass. Nails? Piffle! Razor blades? Come on, that's not even trying. But goatheads? They have been know to make grown men cry.
