Wolf Spider with Egg Sac

I saw this wolf spider in the driveway, carrying her egg sac to protect her spider babies until they hatch. After the eggs hatch, she will carry the baby spiders on her back until they can fend for themselves. There is a nice blogpost about wolf spiders at https://animals.howstuffworks.com/arachnids/dont-be-afraid-big-bad-wolf-spider.htm
