parsley's final attempt at competition was on 13 february 1960 when he entered a 1957 chevy in the 500 mile modified sportsman event at daytona international speedway (now notorious for having the largest crash in nascar history). while nearing the conclusion of lap 1, dick foley's car slid sideways through the final turn. he was able to straighten out and continue the race but some thirty plus cars stacked up behind him. over 20 cars were eliminated, including parsley.
