Rock on Freedom Rock!

I got this pic in an email from a former high school student on mine (took my chemistry class) who is now graduating USC in Foreign Relations, or some such major.

The email he sent says the rock in the picture used to be a graffiti target all the time until it was painted by the artist seen here in the picture.

I hope I can get a few more of these pics posted here at it is a great piece of work. Rock On! God bless the men and women who risk their lives every day to keep me and my family safe. My brother is a firefighter/paramedic in Colorado. Every year I invite the USMC into my classroom to talk to my students. Wish I knew some better way to pay them back for protecting me.
