In 2014, a group of architects and planners created Cards Against Urbanity through a Kickstarter campaign. Per our agreement with Cards Against Humanity, we only produced a limited set, which are gone. However you can print your own!
Here is a link to a LONG pdf. Some tips:
1) use 65 lb. cardstock
2) use a rotary cutter (office or craft supply stores):
3) the cards are printed for 2-sided printing so you can run a smaller set or full set
