CHEYENNE, Wyo. (AP) — Wyoming lawmakers have shot down a bill that called for studying the possibility of creating a state currency to prepare for the possible collapse of the national government.

The House on Tuesday defeated the bill by a vote of 30 to 27. It would have set up a task force to study what the state should do in a range of catastrophes, including the possible political or economic collapse of the United States or disruption in food and energy supplies.

The so-called "doomsday" bill had won initial backing in the state House on Monday after lawmakers removed a tongue-in-cheek amendment that would have expanded the study to address whether Wyoming also should organize its own army and acquire an aircraft carrier and strike aircraft.
