Free Billboards!

But only if you're an anti-gun group:

In April, Moms Against Guns had a humble request: one affordable billboard advertising its petition for stricter gun laws.

Flash forward three months, and the Philadelphia-based advocacy group now has 27 billboards citywide, with at least six more on the way.

The billboards come free from Clear Channel Outdoor Philadelphia and Interstate Outdoor Advertising, two locally based firms.

Hat tip to Sebastian, who has some contact information, and to Bitter, who is asking for more ideas on pro-gun billboard advertising.
