Barking Mad

I know it has been really hot and humid out there lately in the DC area. But can all this heat and humidity cause craziness? You be the judge. I was out doing a lunch time ride yesterday. Just getting in about 45 minutes of moderate spinning. As I was riding along a route that I frequently ride I heard barking. I did not recall ever hearing a dog in that area so I took a glance over hoping that there was a fence. There was no fence but there was a lot of bushes and shrubs so I thought I was safe but I prepared myself mentally for a sprint just in case. Suddenly, it seemed the barking was getting louder and much closer. I thought, no way this must be one big, fast dog to be closing on me this quickly. I decided I'd better take a look back to better judge if I was going to need to sprint. So I look back and what do I see? A guy running after me barking like a dog. He was just giving up. I couldn't believe it. He had a great dog bark. It was very realistic. He fooled me. I just wish I had a photo I could show. Anyone else ever get chased by a human barking like a dog?
