A few goatheads in the Tucson area. More of them in the town of Oracle . . . don't pull off the road there, stay on the pavement.
They seem to be sort of seasonal.
Cactus thorns are a bit of a hassle as they tend to be windborn and end up on the pavement.
Once on our tandem on Oracle Road, my wife yelled "Oww!" Stopped, and she had a windborn saguaro needle stuck in her lower arm.
Have ridden a century in the ABQ area and fortunately did not get any flats.
