As a general rule, the South East Radio Region is further along in the migration than the South Central or Southwest. My guess is that the majority will be "On ARMER" by the end of 2011. As far as the South Central goes, there may be one northern county in the region going full blown ARMER at the end of 2011. The remaining nine counties will all go ARMER throughout 2012.
Don't really know about North Ambulance out of Waseca. My guess is that if there is enough coverage they will switch...Although Waseca County will not be going to ARMER anytime within the next few years.
