I've read my copy several times over the past few years, and have done several other things to expose it to others:
1.  I teach American Government part-time at a local college, and I've put UC on my approved reading list for reports, etc...
2.  I decided that, instead of spending money on parties and such during the holiday season, I would buy five copies of UC and give them to both "gun people" and others who I know would at least give consideration to the content as well as the story.  I think that Borders may start stocking it locally in as much as I order it to the extent that I do.  Have done this for two seasons now, for nine total books (I kept one as a spare and loaner): 2 teachers, one gun store owner, 2 attornies (one a shooter, one not), one trauma surgeon, one commercial artist who had been a liberal until caught up in the LA riots a few years back, two to public libraries (one other wouldn't take it).
3.  I talk about the book with others, both publicly and privately.
