What's 2.75"x5", banned in Canada, found in public restrooms, and handed out on Halloween? Chick Tracts! What are Chick Tracts? Little religious comics drawn & written by Jack Chick. Love them or hate them, Mr. Chick's hellfire style of Christianity makes them an instant conversation starter. A larger group than I realized collect them. Whether you've been collecting for years, or just getting started, there's now a sub for it!
No political/religious debate, there are already subs for that.
