O sorry, I thought he was talking about looking for flint.
I'll bring back some of the other stuff next time and cook it and we'll see what happens.
I'm going to go rock hunting at a friends here in the city. They have a small farm with a dry creekbed running through it. There's lots of limestone for an oven but I'd love to run into some flint too. Wish they weren't calling for rain tonight (well, we desperately need it...I take it back, I hope it rains
).
