Six Flags Magic Mountain is getting into the Halloween spirit. It is the return of their $16 Blood Bag Sangria. Posted on their Instagram page, the drink comes in a bag that looks like an IV bag. The bag has a red cross, the blood type boxes to check and a straw that looks like an IV drip. You can buy the Blood Bag Sangria anywhere alcohol is sold in the park. Is this a creative idea or going a little too far?
