West, around 30 degrees elevation, 10 PM. I've seen the comet the last four nights with binoculars from a not particularly dark site -- urban but trees blocking street lights. Probably visible naked-eye in a dark area.
For directions see the Sky and Telescope map. Use Venus as a starting point to find bright stars if you don't know them. Imagine a vertical line through Procyon, and a line to the left through Castor and Pollux. The comet is a bit above the intersection of the lines.

The Sac Bee published a day-by-day plot of the comet's position but with no background stars or planets. Their mapping skills are on a par with the wisdom of their editorials.
