Colors are sounded each morning at Camp Perry at 0725, starting with the firing of a cannon right behind range 4. Recently they have been better about giving 2 minute and 1 minute warnings before hand, but in the past they have not always been so careful. If you are assigned range 4 and have the first relay that day, I would suggest being aware of the timing of it all. The first year I was assigned that range, lets just say it came as quite a surprise when the cannon went off. If you listen closely you can hear the count down from 5.
