International border intrigue has always been a part of Blaine's ambiance. Smuggling became an underground industry in 1919 with the passage of the Volstead Act banning liquor sale and use in the United States. Rum-running and border jumping thrived along Blaine's shared coastline with British Columbia, due in part to the area's largest whiskey still being located on Texada Island, which is located in the northern Strait of Georgia offshore from the city of Powell River, British Columbia. This continued until Prohibition was repealed in 1933 (coincidentally, the US Congressional law which re-legalized alcohol is named the Blaine Act). In subsequent decades, the situation was reversed due to restrictive drinking and entertainment laws in British Columbia, notably a ban on Sunday drinking, which led to Blaine and its sister border towns of Point Roberts and Sumas booming with taverns and adult entertainment of various kinds. Those days are long gone and now Blaine's retail sector consists of goods such as gasoline, dairy products and clothing outlets, as these goods are cheaper in the U.S.
