I bought two more Pro-2032 scanners just because there was s o much to listen to in my area of the country. Pacific Northwest still has a lot of analog systems, along with the railroads and aviation comms mentioned before. Then there is the proliferation of GMRS radios and repeaters, amateur rag chewers, and baby monitors that have not gone 900 MHz and frequency hopping yet. Many counties public safety are still analog, but I have heard that they will be leaping over FDMA and going P25 Phase 2 TDMA in a year or so, but this only leave a lot of surplus analog radios out there for taxi service, dump trucks, school buses and many others to listen to.
At my desk here at work, I have the two Pro-2032 scanners, a Pro-2040, and a RTL SDR USB stick running SDR# (SDR Sharp) software......the SDR# is on 10m WSPR HF monitoring duty today. There is a lot of analog out there in the world. It is worth getting an analog scanner or SDR stick and running software on a spare computer that can handle it.
