For stabilizing this, I was sideways in the passengers seat of a Subaru Outback. At 6-3, not an easy thing to do.
The better version is in pending with a lot of the branches removed. But I thought that looked "to good" for the challenge. (if that makes any sense)
BTW, the content aware tool in CS6 worked really well for this. it wasn't perfect, but it greatly reduced the time I would have spent using the stamp tool.
