So I recently permanently retired one of my favorite t-shirts. It was from the Museum of the Rockies Paleontology Field Camp program to Camp Makela. My favorite thing about the t-shirt was the "I dig dinosaurs" on the back, which I never noticed for the longest time. I just assumed it was the same as the front.
I met quite a few good friends through the program when I did it in 96' and 97', many of whom I am still friends with today, and I am sad to see the shirt finally die. The program seems to now be defunct, but there is more paleontology field programs than ever for those amateurs (like myself at the time) to go out and learn the tools of the trade.
