Inventor Barry Soetoro, aka B. Hussein Obama, has decreed that his BARRYCADES (Tm) shall be used in outdoor Park, outdoor Monument, outdoor Memorial, and outdoor Mall settings.
However, details have been secretly emerging of past and future plans for Barrycade investments by the boy-toy wanna be Dictator.
Construction of larger Barrycades to be used on the US Mexican Border had to be canceled when the income from the Fast and Furious uncontrolled gun control investment went the way of all other Obamanation investments.
Potential construction of Barrycades to be placed on Obamas Red Line in Syria is currently being jointly studied by the US Military, and Nobel Peace Prize Nominee, Vladamir Putin.
Ambassador Dennis Rodman, no relation to Mrs. Bill Clinton, is rumored to be trying to put together a syndicate of his best friends to provide funding for the construction of these Red Line Barrycades.
North Korea spokesmen would not confirm or deny this rumor.
