Greetings Sonic customers in the Ferndale and north of the border! Sonic has changed management and with the cooperation of Olympic Cascade Drive-Ins will continue to bring you the quality in service that you have come to expect. So hop over the border for a Cherry Limeade and let us know how we are doing on Facebook. Show us why that Cookie Dough Blast is worth it posting a picture on our page, and don’t forget to check in while you are at it. Let us continue to WOW you each and every time you drive into an OCDI Sonic.
