I don't mean this in a "so you can leave the country!!!" sense, but given all the fucked up stuff with ID coming from the states (voter ID laws, obtaining driver's licenses) and the Feds (PA driver's licenses will soon not be valid as ID to fly, for example), get a passport. Make sure you kids have passports. Renew them all if they're expired.
Also, too, if you're a noncitizen resident eligible to apply for citizenship, do that, though for not quite the same reasons...
