This graphic by Jill McAllister is extremely meaningful, as it provides information not currently available in terms of geographic distribution of Lyme and Lyme infected ticks.

Some of these locations, although across the border, are not really all the far from where I was bit in 2010 (various maps will be constructed over time).  As you will read elsewhere on this site, distribution estimates and maps can be dangerously misleading if they do not depict associated levels of detection effort.  As is seen time and time again (with North Dakota serving as a highly relevant example) the areas where we are not finding Lyme coincide with areas where we are not yet, or not adequately looking.
