Other than police operations, there are some analog talk groups used by state fairgrounds employees, mostly maintenance. They are used year-round but of course are busier now.
According to local news reports, thefts from cars parked in lots near the fairgrounds are rampant.
You will also hear IPD on MECA being active near the fairgrounds. Needless to say they are very busy!
I don't know the analog talk groups for the FG but they should be in the SAFE-T database.
