On April 1, Defendant is stopped in South Carolina driving north in a '72 VW microbus with a marijuana sticker the size of a thimble on the rear bumper. Agent can't see inside the vehicle, and asks Defendant to open the back door to allow examination of the vehicle's contents. Defendant declines unless Agent can produce a search warrant.
Agent asks if Defendant has drugs in the vehicle.
Defendant asks whether he can't just go on down the road about his business. Agent says he will have to wait about 10 minutes for the dogs to arrive. Defendant explains that vehicle is old and starts unreliably, and that if he turns off motor he will likely be stuck here until a tow truck can come. The dogs are having some routine yearly nasal aspiration, which has been scheduled for the last week in March but was delayed due to one dog being sick, and don't arrive for five hours. Inside, Agent finds drugs.
