One central Illinois town wants to be a local as it can be.  Normal's Town Council has adopted a local preference purchasing policy, or a buy local first plan.  City Manager Mark Peterson says the local first idea is one part of the sustainability plan adopted earlier this year.  Councilman Jason Chambers says the policy is more about disclosure, adding "If we did have an out-of-town bidder, then it's just giving notice we might give some preference to people locally."  Other councilmen hope the local first policy will save Normal some money on everything from fuel to food to raw materials.
