PRobably because you didn't breakfast on "Old Massachusetts" - I don't know if it possible now - but there was a petrified tree we were allowed to climb on - labeled "Old Massachusetts" for some reason I don't remember - but it had a broken section we immediatelly dubbed "Cape Cod" - and we had a picnic breakfast on the trunk.

The day we "did" the Petrified forest we also visited Meteor Crater and ended up at Grand Canyon National Park (in time to catch an evening lecture and watch the Echo satellite). sometime during that day we also visited another national park where we got to play with a bat. It was a busy day - and my parents did it with 8.25 kids in the car and towing a 24 foot travel trailer.
