The guy at McDonalds may ask "Are you serious?" But a half strawberry, half chocolate milkshake is actually pretty good. Just ask Steak n Shake. The best part about it is you get a slightly different flavor in every sip.
This is a tip for those who might run where giant swarms of gnats sometimes loiter by the side of the road. This tip stems from a run on the Mayan Riviera in Mexico, but I've encountered swarms of gnats in Virginia and Kentucky as well. After your run, always stop and look in a mirror before going into public. Otherwise, you might actually complete a transaction at the resort store and greet five people before realizing you have up to 15 gnats stuck to your face and neck.
