The stress of not being able to reach your wife, particularly with her illness is terrible. If they lost electricity, they may have turned off cell phones to conserve batteries. There have been widespread telephone overloads due to the storm. If you still can not reach them, you may want to try local emergency management for a status report on phone services.
Thank you both for your input and concern. I just recd. a text message saying “We’re OK”. Brief, but puts my mind somewhat at ease.
