DMR and NXDN are handy if you want to monitor electrical utilities' operations during power outages. SETHRA buses are a good listen if you want to stay on top of traffic conditions, but you'll need DMR. Don't bother to take a scanner on a Mississippi Gulf Coast vacation (Biloxi) unless you have ProVoice. Casinos are a big user of DMR, but some, such as Murphy, NC, are encrypted.
