Biscarrosse (my latest stop) is notable for a couple of things – one is a big oil reserve and the other a rich history of seaplanes.

Just like Foynes (the wikipedia entry reads:)

During the late 1930s and early 1940s, land-based planes lacked sufficient flying range for Atlantic crossings. Foynes was the last port of call on its eastern shore for seaplanes. As a result, Foynes would become one of the biggest civilian airports in Europe during World War II. Surveying flights for flying boat operations were made by Charles Lindbergh in 1933 and a terminal was begun in 1935. The first transatlantic proving flights were operated on 5 July 1937 with a Pan AmSikorsky S-42 service from Botwood, Newfoundland on the Bay of Exploits and a BOACShort Empire service from Foynes with successful transits of twelve and fifteen-and-a-quarter hours respectively. Services to New York, Southampton, Montreal, Poole and Lisbon followed, the first non-stop New York service operating on 22 June 1942 in 25 hours 40 minutes.

But Foynes has another claim to fame (unaudited!), Irish Coffee:
