One of the great joys of summer is when you can take some time off to hit the beach or a local park to have a family picnic or a romantic picnic for two. A possible problem could arise if it has rained recently, and the ground is a bit wet. It is at those times that a waterproof blanket can be very handy. These blankets can also be used on car seats to protect the upholstery if you have been swimming and your bathing suit is still wet.
