Yes, people always seem to get in the way. Unfortunate, but it's why we are all there. Very nice shot with the station, the light fixture in the center is nuts - I can't imagine the 'fun' they had wiring it up.
Yes, it doesn't need to be medium format, it's just the best camera I have, and the next option would require 4x as many shots and 4x as long to get the same size.
