Memorial Rock Dedicated to Our Military

Hey Dad,

We saw this rock being pulled behind a pick-up truck last week on I-35 South near the Oklahoma Kansas border.  On the back it said “Dedicated 14 April, May or June 2011, couldn’t read the whole thing since straps and cardboard were covering it.  We had to take a picture with my iPhone as we pulled-up next to it going about 75mph.  The guy driving the truck looked to be Vietnam vintage and had a Marine Corps sticker on his rear window.  Pics came out pretty good for that speed, of course it is all about relative motion.  Not sure where this rock was going but it was pretty cool to see the American spirit in the heart of the midwest.
Love Joe
