Goathead=very nasty thorn with 3 points.....shaped like a goats head. It's a very hard thorn so it's very easy to have the points break off like....in my thumb or in a tire.

SBC - crossing fingers no flats for you either. If it helps, I finally bought Kevlar tires And I use slimed tubes. I still pick the nasty little boogers up but I don't have flats. Now if I could just get the thorn out of my thumb I'd be a happy camper.
