My brother earns his keep fishing for bass in AZ and CA. He was just telling me this evening of a day in September of last year on Bartlett lake. It was the end of monsoon season and there was a bunch of thunderclouds building. He picked up his graphite spinning rod to fish and it started "humming". He said at first he thought it was the wind making the line whistle but when he put the tip straight up in the air he got a shock. Nothing big, but he definitely felt electricity..... Needless to say the fishing stopped for a while while the storms played themselves out.
