Oddities of U.S. Borders, Part 2

There are two "international parks" of interest on the U.S.-Canada border. The International Peace Garden, on the border between North Dakota and Manitoba, basically exists in the "no-man's land" between the two countries' port of entry stations. Visitors from either country may enter the park without stopping at Customs, but must stop at the appropriate port of entry when they leave the park. I suppose it would be possible for someone to get stuck in the park, not being able to enter either country. While in the park, visitors may cross freely back and forth across the border line.

Another international park is Roosevelt Campobello International Park, in New Brunswick. Although the park is entirely in Canada, it's normally accessed by crossing the border bridge from Lubec, Maine. There is also a car ferry that connects Campobello Island to the New Brunswick transportation system via Deer Island, but it only runs during the summer. The site is also unique in having been the only summer home of a U.S. president (Franklin Roosevelt) to be on foreign soil.

There are three airports that actually straddle the international border. Between Minnesota and Manitoba, Pinecreek Airport started out wholly within Minnesota, but was extended into Canadian territory. Customs offices are adjacent to the field. A similar situation exists between Washington and British Columbia, at Avery Field State Airport. The one airport whose runway actually follows the border is Coronach/Scobey Border Station Airport, between Montana and Saskatchewan.
