It's in the direction of the constellation Monoceros (Unicorn).
Using binoculars or a telescope,look slightly south of an imaginary line between star Procyon and star Betelgeuse, about 2/3 of the way toward Betelgeuse.
In Mid March, in the mid-latitudes of the Northern Hemisphere, you'll need to look after full dark but before 10:30 PM.
BTW, light pollution WILL blot out your view of the nebula.
