Romo beach, it may not be as big as El Mirage, or as famous as Bonneville, but it looks pretty big from here. And, this is the first I've ever heard of it

The extensive beach is the setting for the Motor Festival – the revival of a historic car race that took place on the island of Fanø (in Denmark) from 1919-1924
