I was part of a summer camp that was run in conjunction with the local university where we got to design a museum exhibit and put it on at the university's museum dedicated to anthropology and culture. We got to choose the theme of the exhibit (which didn't have to fit the museum) and chose the local fossils since they were easy to find in any creek and we all loved going out and hunting them. I remember my part of the exhibit was crinoids, and I wrote the title card and designed the display- the crinoids fossils were in some sand. I don't remember much else because we're talking almost 40 years ago. But I remember how awesome it was to be in the museum and see people looking at my display.
