Good call on delaying it. I doesn't look like it will be good weather and flying in bad weather or getting everything in place when the odds for good weather look so bad does not make sense.
However, in case any of you were already going to be in southern Utah or the weather is better than expected this coming weekend there is another fly-in/airport open house that you might want to consider at the Escalante airport. According to the sponsors they are going to go ahead with it regardless of the weather and are having a free dutch over dinner on Friday, free pancake breakfast on Saturday and a free catered diner on Saturday. There are discounts on lodging for the weekend for anyone that wants to spend the night and not camp. Call Paul for more details at 435-826-4662 or check the Utah Back Country Pilots website
