It is no longer true that I've never seen them there in the summer; and not just whimsical of me to look carefully every time I drive through, Just In Case. :-)
No pix. They were far back by the trees, flashing their beige back ends towards the highway. I was eager to get to the ocean, so I didn't stop. Hoped they would be still there and better located when I came back a few hours later, but they were gone.
