Checkout the website "http://www.freemaptools.com/radius-around-point.htm". You can give it an address and a radius and see what is encompassed. Granted it is not road miles, but still gives you an idea of what is in range of a particular radius of travel.
I built this arrangement for myself, and when I showed it to my brother, he asked me to make a "travel kit" for him as well since he's on the road a lot.
I'm curious how many others would be interested in obtaining a "Plug-N-Play" Plug kit for their Level 2 chargers.
