In a nutshell, if you consistently deny the noncustodial parent his/her visitation, and then you move halfway across the country with the children without permission of the court, don't be surprised if you lose custody of your children.
Note: An interesting fact in earlier proceedings between these parties early in this opinion. Note that the trial judge in 2004 found the mother in contempt for failing to comply with court ordered visitation. The punishment? Community service! First time I've seen that one in a domestic case. Maybe not a bad idea.
