I am planning a trip with my 12-year-old grandson (and future paleontologist) to a dinosaur dig this summer, and would like to get some first hand advice on choosing a good outfit. We can go about anywhere in the U.S., several days to a week, but since we'll likely be flying we can't easily bring along much gear of our own. I've researched dozens of dig sites. Some sites were outdated, some sketchy on details, some had age limits or are already filled. PaleoAdventures and Hell Creek Fossils, Dinosaurs of the Western Slopes are possibilities, but I would welcome any comments on organizations to avoid, or ones you have had a good experience with.
