FeralRobots@goatsarah This is a fun question. Unless I'm mistaken the answer for North/South America is probably Prince Edward Island, in the Canadian Maritimes. There are much bigger islands (e.g. Baffin Island), some of those even more important (e.g. Newfoundland or Long Island [in New York state]). Caveat that I haven't looked at Tierra del Fuego to see how much of that one can get to by bridge/tunnel.
