It looks like the tax rate for the Litchfield Area Ambulance Special Service Board is headed up.  In a narrow 5-4 vote, the board agreed to triple the maximum rate to 45 cents, generating a potential $648,000 for the service, which is battling a $300,000 deficit.  Critics on the board argued the service should be self-sufficient while supporters were concerned about potential service cuts and a pattern of city revenue supporting ambulance service. Voting for the motion were Dave Hollo, Kassidy Payne, Tim Wright, Woodrow Street and Robert Buda. Voting against it were Marilyn Sisson, Mark Brown, Ray Kellenberger and Dwayne Gerl.
