CBS LAS VEGAS-It’s the day after Christmas and the City of Henderson is telling residents to make use of its free Christmas tree recycling program that runs until January 17th. This past weekend San Francisco and Oakland were giving people $200 for their guns. The line was so long in San Francisco that after lunch time they were handing out I.O.U’s instead of cash. Would you sell back your gun to the Government for cash? Callers tell us if they would participate in the buy back.
