Tentatively yes, maybe only the short run depending on how many full trips to/from work I do this week. Wouldn't mind peeling off at Wilcox Lake and going around Sunset Beach Blvd, it's beautiful around there and would be a fantastic spot for a break/safety meeting - That can be done another time though, if the objective is to do the donut ride, I'll do it as a complete run.

Edit: looking at the routes, it goes down Sunset Beach already so nevermind - there's always a choice to stop or not.
