Colorado Cactus

Who knew that Colorado has cactus? I didn't prior to moving here - I didn't think it was dry enough here for them. Yet there they were. Where Apollo and I were walking - on a foothill - we had to share narrow trails with bikers, and I was worried Apollo would blunder into one. He has NO experience with this kind of thorny problem.

Because the grass blended in with the cactus, I burned it - in photoshop, not literally - so that the cactus popped out more, visually. Easy, quick and effective means if your photo subject is blending with the background.
