In the time-honored tradition of the "What I Did on Summer Vacation" essay, Clark opened the show today by talking about how he spent the summer break. This summer found Clark and his family at their beach home in Florida quite a bit. They also took a trip to San Francisco, where Clark and his wife visited relatives and did a lot of walking. Now that his family's vacation time has winded down, reality has set in especially hard for his teenage daughter. She's off at college for the first time this year. Unfortunately, she got a $77 parking ticket during her first day on campus because she didn't have a parking pass. Talk about the school of financial hard knocks! On a related note, Clark often chides his daughter when he sees her with bottled water. There was a recent study that compared the cost of drinking bottled water to the cost of drinking tap water. Consuming tap water will run you about 49 cents for the entire year, while drinking the same amount of bottled water will burn a $1,400 hole in your wallet! Many people still prefer bottled water to tap water because of taste and/or safety issues. In fact, Clark's beach home has notoriously bad tasting tap water. His solution? Just use a relatively inexpensive filtration system to clean up your tap water and make it taste great. Clark wants everyone to consider this option -- especially as more and more brands like Aquafina and Dasani are revealed to just be tap water in a fancy bottle with a huge price markup. Who wouldn't want to save $1,400 a year?
