There is some overlap between Geocachers and Amateur Radio in
Nova Scotia as witnessed by the Truro meet on Amateur Radio Field Day...

Nova Scotian Amateurs make some good use of IRLP, (Internet Radio
Linking Project) to transmit via internet connected repeaters to far
flung locations. So you potentially can be geocaching in New
Brunswick and talking to someone doing the same in Ontario,
something you won't find in CB radio.
