wooden posts, ala, "the west clay pit" or some such, but if the park folks were going to go to the trouble of put up a sign for that, you'd think a helpful "fossil area" would be useful too. still, it kind of added a treasure hunt aspect to the whole experience.
we had a great time. like any good fossil hunters, we got sun baked and dusty. a success for most six year old boys, i should think. i think it helped that mason knew the sort of things we'd find yesterday. despite all my big talk about hunting dinos, he did *not* have his heart set on finding t-rex.
