We are in the process of introducing "dynamic standbys". Basically someone in a nice air conditioned and comfortable office somewhere has got a map of the area, drawn big circles on it and in the centre of every circle placed a car or ambulance so that the mighty god ORCON can be appeased. It works really well.... (can anyone hear the sarcasm?) last week they sent me to sit at the roadside in a little town. It was very pretty, I got my book out and started to read, only to get a red call back where I was originally, and I missed ORCON, oh well the computer obviously missed that call when it was considering were to place me next!!
