I dropped my cell phone in the sand the other day and
didn't notice it until minutes after it had departed my
pocket.
I was freaking out!
After retracing my steps on the crowded beach for a few
minutes, I actually found it. Woo-Hoo.
Maybe you should head back into the Sahara and look

It worked for me! Then again, I've found hundreds and
hundreds of dollars in the sand on the same beach. I think
the sand likes me in Pacific Beach.
