So, what we did was, once we got the money allocated through Congress for the study, several of us, on the first trip let me think who all was involved on the on the first trip to take the Bureau of Outdoor Recreation study team down the river. We got Texas Outward Bound to furnish the rafts and some and some raftsmen to carry the government team. Then John Baker, Dr. John Baker, a dentist from Dallas, my cousin, Harry Burleson, let's see, I think Bob Sims, friend of his, Davis Bragg, number of other friends, that we boated with a lot. David Riskind, we all kind of put together a team and we took the Bureau of Outdoor Recreation study team down the river, Rowland Rower, former at that time, I think he was Chief Naturalist at Big Bend National Park. He was there and there was some other national park people.
