"Awesome poem. Did you write that?"

This poem was written by Corporal Joshua Miles, 3rd Battalion,2nd Marines and his buddies. It is titled Wish You Were Here..Your question sent me searching..
I found it featured in several blogs and one TV station site..The one above is beautiful and contains an explanation from his parent. The poem is a little past half down as you scroll.
Thank you for asking because I was happy I found the source. The screen got a bit blurry.
It is also on this Support site.
