There are two living species referred to as minks: the American mink and the European mink. The extinct sea mink is related to the American mink, but was much larger. All three species are dark-colored, semiaquatic, carnivorous mammals of the family Mustelidae, which also includes weasels, otters and ferrets. The American mink is larger and more adaptable than the European mink. Due to variations in size, an individual mink usually cannot be determined as European or American with certainty without looking at the skeleton.
At just under 4.5 miles, the Road America course in Wisconsin is the longest track in NASCAR. The longest oval track in NASCAR is Talladega Superspeedway in Alabama. It is 2.66 miles. Written Aug 8, 2015.
Most NASCAR tracks are 1 1/2-mile oval tracks. These are referred to as speedways and usually see track speeds topping out at or near 190 MPH. Atlanta Motor Speedway is the lone exception, due to its longer backstretch than most 1 1/2-mile tracks, and has occasionally seen speeds pushing 200 MPH.
