So what’s Sen. Quinn getting upset about? Well, as it turns out, the federal government issues licences to two tour-boat operators that land looky-loo tourists on shore, one from each of the countries that claims Machias Seal Island. The licensed American outfit is based in Maine, and its website invites nature lovers to come see “the largest puffin colony on the Maine coast.” Moreover, it informs visitors, accurately, that “no passport or other form of identification is required to visit the island,” which has no customs apparatus.
