If we went back, I'm sure it would not be with single stage missions like Apollo. I'd like to see us shuttle up and assemble a much larger kit in orbit, probably at the ISS, then boost our way there when we are ready. Maybe even set up a kind of supply run system, shuttling people and equipment back and forth between Earth orbit and the Moon.
