Frank Morris, Clarence Anglin and John Anglin — assuming they are still alive — would no doubt be amazed about the never ending throngs of people who plunk down money so they can get to Alcatraz.The trio is part of the historic lure of “The Rock” — the 957,988-square-foot island in the middle of San Francisco Bay that’s smaller than an Amazon fulfillment center. They are the only three to ever stage a successful escape from the former federal prison although it never has been determined whether they survived the frigid bay waters to make it ashore to enjoy their freedom.Alcatraz is arguably one of the world’s most famous islands. Originally a lighthouse, then a military fortification before becoming a military prison, it’s transformation into a federal prison from 1934 to 1963 established its global reputation as a foreboding place just 1.25 miles offshore from one of the world’s most cosmopolitan cities.Hollywood helped fuel Alcatraz’s lure with a slew of movies such as “The Birdman of Alcatraz”, “Escape from Alcatraz” and “The Rock”.
