Umbrella policies are great. I have one, but I'm not sure if I'm covered when playing, because I'm not driving or in my home.
I know the umbrella policy does not cover equipment when playing. It's covered when transporting in the vehicle that's insured.
I had a drunk once pull Pa speakers over on himself and a beautiful 335. I paid for his trip to the ER to get checked out. He was ok; the 335 wasn't.
OH, the drunk was a friend.
