Yes it was quite something, particularly away from the cities. It was also something to see crowds of people at places like Yosemite National Park at night getting views of the comet. Anyway, I managed to try to capture it in a sketch of how it looked by eye - although I'm afraid I'm not good a drawing - which is just below. One thing it reminded me of at the time (when looking by eye) is the appearance of hot glowing exhaust from a jet engine, although instead of focusing into a cone it fanned out - if that makes sense!?
