Unlike the businesses that occupied the lot before it, Carl's would flourish and become a city staple for the citizens of Fredericksburg and tourists. Since its inception, Carl's has only served three classic flavors: chocolate, strawberry, and vanilla; however, they also serve slushies, malts, milkshakes, and sundaes2. Carl's is a part of a mid-20th-century historical movement propelled by the automobile industry, because of its location on Princess Anne Street, which is the product of the boom in superhighways developed by the Federal government in 19441. These superhighways were bordered by gas stations, shops, and drive-ins that accommodated travelers. Moreover, the automobile spurred on the ice cream industry because more people were able to travel long distances and enjoy food on the road, or recreational eating that began to gain popularity during the Civil War, but was revolutionized by the automobile. Indeed, Carl's is an ice cream stand, which is unlike the Dairy Queen corporation restaurants; coincidentally, the Dairy Queen that would open in 1950 on Princess Anne, along with several other ice cream or custard places would close down, with Carl's the only one remaining on this street1. Indeed, this inside-out design is intentional, rather than having an indoor restaurant with the typical decor and furniture, Sponseller chose to affix the giant curly-cued ice cream sign atop the roof and use vibrant yellows and greens for the stucco walls to attract as many hungry stomachs of Fredericksburg as possible.
Carl Sponseller was not a person persuaded by change; in fact, the Electro-Freeze machines that churn out the ice cream every day have been used since the stores inception and were created in the 1940s. Sponseller's persistence and unwillingness to compromise is illustrated through the continued use of his original recipe for custard, despite the industry's change in custard recipe standards--to four percent egg yolk. He simply shortened the name from Carl's Frozen Custard to just Carl's to retain the right to continue his original recipe1. Customers should be aware that only cash is accepted, because the store is not equipped with credit card machines. The restaurant is still owned and operated by the Sponseller family through Carl's brother,Paul Sponseller's children, and the family is dedicated to Carl's reverence for hunting season; therefore, the ice cream stand remains closed from the Sunday prior to Thanksgiving to February 20th, Presidents Day1 2. The popularity and creamy goodness of the ice cream sold at Carl's also continues to remain.
