I'm told that there is a huge rock near a gravel pit on Hwy. 25 in rural Iowa. For generations, kids have painted slogans, names, and obscenities on this
rock, changing it's character many times.
A few months back, the rock received it's latest paint job, and since then it has been left completely undisturbed. It's quite an impressive sight.
Click on the link below and check for yourself. There are multiple photos (all angles) of the rock.
Hope you enjoy!
