Inconvenient, but stylish

ok, it wouldn't be extrordinary for me to write a whole post about the shift in the hardiness zones and how here in Chicago we were a 5 and now we are a 6. But what I find really unusual is the pattern in the map that shows the areas in which there was a change. Yellow is no change, pink went up one the light blue went down one and red went up 2. Look how stripey we are. Isn't that odd? Like someone batiked us. Does anyone batik anymore? Should I use tie dye as a better reference? We are tiger striped for the most part...
