I don't know exactly what you are interested in listening to,but if you want to listen to MSP units you would more than likely hear more traffic on the individual countywide TGs of the counties they patrol. The Lansing post patrols Ingham,Eaton, and Clinton counties so say MSP 1144 gets dispatched to an unknown accident on I-96 and M-52. Most of the time,all the the dispatch info would be sent to them on IC MAIN of the Ingham county public safety trunked radio system for that individual call. I'm not saying that their isn't anything interesting on the statewide TGs though,just saying if you are going to be in the Lansing area,you may want to monitor the county networks also.
