The province has released an updated map that outlines (what they believe) to be the areas of the province where you're most at risk of potentially catching lyme disease if you get bit by a tick and don't get it off you in time. Not sure how accurate this map is, as I seem to recall newhunterette talking about her struggles with Lyme disease a few years ago, and if I recall correctly, she believed she got bit in the Cariboo, and according to this map the Cariboo is not a hot spot. Regardless, hopefully this might be helpful to some - always a good idea to double check yourself after a day in the field wherever you're located in this province
