The 146.970 isn't really statewide, the repeater is located in Indianapolis so from Crawfordsville, you may need a good outside antenna to receive it. It is used to cover the counties under the Indianapolis National weather service office, like what W9NES said.
W9NES is also correct and that your local traffic is on your local repeater and one person from your area will report to the statewide net on 146.970, weather that is reportable in your area, and at the end of the local net, report how many check-in's your local area net had. 146.97 is really for the NWS and reportable weather. It is fun to listen to if your area is not under the gun of severe weather and other areas are, or it can help you determine when severe weather may hit your area. They usually tell the local counties when to bring up the local nets and when to close them.
