PLEASE talk to a lawyer before just moving out of state. I worry if you just head off that you could be seen as abandoning them (regardless of your actual intent) and just because your W verbally agrees to you having them for the summer....doesnt mean that she will sing the same tune in a few months/years when thats put to the judge to decide. If she says that you just left, do you really think youll get custody for months at a time?
