wow.. I assume they dont go crazy if they see birds etc? Does anything spook them?
On a slightly related note, there is an Aussie book written by Peter Haran titled "Trackers" The untold story of Australian Dogs of War. It is about his time in Vietnam in 1967 as a dog handler and has some humorous stories about getting into and out of Hueys.
TFS.. thats a great pic too!
