If you have young children, this may effect you more than those who don't. Prepare by having plenty of games available, and be willing to play. It may also be a good time to read to them, teach a new craft, etc. Whatever, expect to have to be the sole source of entertainment for yourself and your family. During any sort of an emergency, information becomes extremely important.
Radio is more likely to be available.
The best defense is a good offense. Don't count on your paycheck, social security, child support, etc., payments to be there. If you live from paycheck to paycheck like many people, you'll be severely hit if the money doesn't post to your account as scheduled. As difficult as it is, set enough cash aside to support you and your family for however long you feel is necessary. Make sure to get hard copy receipts for your records.
