Somewhere in Mexico, south of Mexico City.
There I was minding my own business, cruising along at 9500ft and the darn trees started getting bigger and closer. Fortunately none were the ill famed "Mexican Jumping Redwoods". I did get close enough to the top of one hill there that had a farm on it, I could have stole a watermelon. Any lower and I've have plowed the farmer's fields with the props.
