"He who marches out of step hears another drum." ~ Ken Kesey
That is so funny, we've had state farm as a family FOREVER and it's seriously been the easiest insurance I have ever dealt with(home, auto & boat). Business liability/health/etc have been terrible.
The reason you see so many insurance commercials is because people shop and switch insurance companies very frequently. I forget the number, but something like people switch on average, every 6 months or something crazy. Feel free to correct me.
