OK this is mission impossible but let's give it a try for the sake of the game :)
The picture doesn't say much, at least not to me that I live on the other side of the world so it's only your blog that can give some clues. Unfortunately you don't post too often and the info about your moves are very limited!
Nevertheless I have decided to make a guess and I will :)
You live in Utah but you said that you were visiting a project out of state, so it is not in Utah. The only project that I have found mention of, is a school in Minnesota which you have visited and taken some pictures of it. This is also a dead-end because the pictures of the school are taken in winter and the one in question is definitely not. But I'll pretend I didn't notice that and I'll continue :)
In your post about the school you don't say where is it but in a comment you provided a link that informs us that it is the Southwest Christian High School in Chaska, Minnesota.
And that's as far as I can go!
So my answer is Chaska, Minnesota although it is rather unlike to be correct :)
That's some good detective work.
