You could try joining or volunteering with a libertarian group. Each state has a libertarian party, and then there are a lot of national libertarian groups. ATLAS as an example has an annual conference every year in New York that is well attended. Americans for Limited Government. Atlas Economic Research Foundation. Cascade Policy Institute. Cato Institute. Centre for Independent Studies (CIS) Center for Individual Freedom. Center for Libertarian Studies (CLS; defunct) Competitive Enterprise Institute.

I would venture to say a lot of people don't know what a libertarian is
