We read this article and thought, if we could draw like this, we'd be traveling the world with a sketch book instead of a digital camera, too.
The sketches of Carl Steinitz, a landscape architecture professor at Harvard, were featured in the June issue of Landscape Architecture Magazine.
The professor's favorite locales to draw? Piccadilly Circus in London and Piazza San Marco in Venice.
If you're up to the task, try Professor Steinitz's method the next time you take a fantastic vacation. You'll cherish the memory.
