SM and I traveled to southern Utah at the end of January.  We stopped at a rest stop along the way and I just had to take a picture of this huge crow on this sign.  The crow was neither on the lawn nor in the restrooms so I was wondering, who had taught this crow to read?  A little later the crow found the garbage can and manipulated some garbage out of the can and found a yummy apple core to eat.  This was one amazing scavenger!
