So it was all very interesting, but it was not nearly as extreme a sport as I had expected. A lot of it was floating downriver and listening to the river guide. Turns out we were given a condensed version, and not the most exciting part of the river. 4 rapids in 2 1/2 hours. Too much talk as far as I was concerned, and not nearly enough excitement. All in all, a bit of a time waster. I can't see promoting them having not had the real tour, and I don't appreciate their use of my time this way. After the experience, I thought the (theoretical) price was high, and then was told that we were not shown the best part of the river for action.
It was nice to be on the river for an afternoon, as that is a rare experience for me.
"The lads" are my current volunteers. One is from France, the other from New Caledonia. One is a construction supervisor, the other a mechanical engineer. They are very skilled people, and I am blessed to have them here, fixing things that others, who were paid, did not do correctly. If anyone wants the name of a couple of lousy contractors, I am compiling quite a list at this point.
