I once knew a man who was going to a school of higher education in pursuit of a degree in Cartography.
"Don't they pretty much have it all mapped out these days?" I asked.
"Yea, for the most part," he replied.
"So is there much demand for cartographers anymore?" I asked.
"Oh yes, very high demand," he replied.
"Are you mapping the depths of the oceans, or perhaps outer-space?" I asked.
"You sure do ask a lot of questions," he replied. "And no, we aim to remap the Earth more efficiently."
"They have Google Earth available for free on the internet," I said. "Total satellite imagery of the entire planet."
"Is my pizza ready yet?" he asked.
