take a look, charging stations have been popping up all over. (the leaf actually displays them on the map w/gps and directions), plus plenty of android/iphone/website options. And probably there is at least 120v somewhere for a 1.5kw topoff at your friends/families house, or install a 240v outlet for 'em if you plan on frequenting them.
