Rooster, the cross you have a picture of, is quite impressive, in its own right. Don't think you could have church in it though.
I pass this cross, a couple of times a year. It is on I-40, between Oklahoma City, and Amarillo, Texas. I think the town is Groom, Texas. It is worth stop, to look around. There are also the 12 stations of the cross, done in bronze, all around the large cross. They have a contrabution box, at the exit. (hmmmm that sounded familiar)
