In Frederick county Md, the busses and school resource officers are on the county P25 but the schools themselves have their own radios.  Some FMN and some DMR.

Well, if you use something like unitrunker or other software with a couple of SDRs, you can often find talk groups on trunked systems that aren't in RR.  For other things, scanning, both the air waves and the FCC license database is the way to go. When you do confirm, be sure to submit it to RR.
