From 1960 to 1978, Blackmer was a dominant force at both Stateline Speedway in Busti and at Eriez Speedway in Erie. He roamed those tracks in his memorable "4" and "4JR" cars and only a scant few drivers were able to challenge him over his 18 years behind the wheel. His peers at that time included other well-known driving legends such as Squirt Johns, Skip Furlow, Bobby Schnars, Johnny Whitehead, Jay Plyler and Sammy LaMancuso to name a few. The Youngsville, Pa., native racked up 133 feature wins in the Sportsman Division, almost three times more than his closest competitor. He also won four Sportsman championships at Stateline and six at Eriez, along with four S-E Circuit Sportsman championships. He also collected 62 second-place finishes and 26 thirds along the road. Blackmer won 27 Late Model Division feature races at Stateline and Eriez and at the time of his retirement, only two other drivers had won more. He also took home two Stateline Late Model titles, three more at Eriez and two S-E Circuit Late Model crowns with only one other driver topping his record. His success wasn't limited to the Stateline and Eriez tracks. Blackmer also won plenty of races in Olean, Wattsburg, Warren, Smethport and Roll-O-Bowl speedways. At Wattsburg and Smethport, he collected more track championships. Blackmer also competed at other race tracks in New York such as Arkwright and Coon Road; speedways in Pennsylvania such as Tri-City, Lernerville, Bradford, Clearfield, Marion Center, Port Royal, and Mercer; Ohio tracks such as Eldora, Raceway 7, and Mansfield; and Parkersburg in West Virginia.
