I've had that happen a coupe times also. We were out bass fishing with a storm blowing in, and definitely an electric field ahead of the rain. Our lines began to hover above the water and you could feel the rod vibrate a little. My buddy screamed at me to drop the rod!!!!!! Guess another buddy of ours was fishing before a storm when the same thing happened, and his rod "Blew up" in his hands throwing graphite everywhere. No injuries but most likely a pair of soiled britches.
