In the interests of transparency, here were my ballpark assumptions: 

A typical Double Corona is almost 8 inches long
A typical Double Corona takes about 90 minutes to smoke assuming a reasonable pace
The cigar mentioned below is 1704 inches
More controversially, I assumed there were 12 inches in a foot, and 60 minutes in an hour

All that math in order to justify posting this item from Luxist about a new world record for rolling the longest cigar at 142 feet. Previous record? 67 feet. Goal for next record? 6 miles. I'm still crunching the numbers on how long that would take to smoke. Stand by...
