How practical would it be for IM to apply for permits for Sat and Sun, and then 1-2 weeks out they would settle on an “official” day, weather dependent? Have the race planned for one day, but if there is severe weather on the horizon, you have a backup plan secured. This would not be “well Saturday looks like it’s a little better temp so let’s do it then instead.” It would be reserved for truly dangerous circumstances like this.
