You all have great ideas for mapping and how to learn your area. I respond with two different services in two different counties and they both dispatch differently. :? So to be able to use all of your ideas to create two mapping systems one for each county to have in my vehicle with be of great help and save time for the patients waiting for care. I do try to watch road signs and make mental notes of the roads when I am driving through the counties, but it sometimes that is hard to recall when you are going to the scene and you are in full EMT mode. Thanks for you great ideas.
