Petra does have a lot of good intuition, Don, but don't put down scientific logic either.
Your prediction for Kalispell may yet beat out Petra's intuition for Helena. An earthquake
happened at both locations in the stated time frame. What is left to be determined
by the Montana Bureau of Mines is just how big that Kalispell earthquake was -
that will determine the winner of yours and Petra's contest. It could be a week before
the Montanans publish their results, so don't hold your breath.
