Try that anywhere in New Mexico! You will know real pain and what a goathead is! They have reached as far east as the Gloss(Glass) Mountains of Oklahoma!
They had them in California where I was born and raised and here in Arizona. When I first bought this house they were all over the yard and they’d get tracked in the house and stuck in the carpet, but after two years of pulling them up the moment I see them in the yard, they’re now largely under control. I hate them so much, even when I see them in other peoples yards I feel like pulling them up!
