Cash the bond. or not?

if you really need the money i say cash it and put it into a money market account because then you can pull it out of there anytime you want, but if you are not desperate for money keep it because my friend kept his for 30 years and aculated 6 times more than what it was originally worth. Your not going to make that much more money on the money you would cash it for and invest it unless you are a risk taker and put that money right into a high risk investment. Thats just my experience with bonds.
