The monsoon is going nuts tonight. I am getting pounded by lightning strikes. At least one or two a minute, and they are close and loud. It's rattling the windows. I have a question, why does thunder go on for so long? I can hear it continuously for a good 10-15 seconds. I thought maybe it was just because of echos, but then I noticed that is starts quiet then booms then quiets. Echos can't get louder than the original sound can they?
