We're just getting on the FB bandwagon at PSR. One thing I've noticed while playing/testing with it is that when I run FB at Step 5 (non precip types), the Step 5 GUI that comes up does not include PotBlowingSand or PotBlowingDust check boxes. Is that in the local configuration? Seems like each Pot* has a tool to go with it, if there isn't one for dust, seems like a good opportunity for southwest offices to provide some effort.
