Thanks and...well

I am thinking gradually put in enough money so that the 6% per year turns into $30,000 each year (so that I can have enough to buy food and pay for gas).  Won't get rich, I know, but it is a steady stream of income. 

Plus -- these muni bonds from my state (Texas) sound fairly safe.  No major default that I've come across yet and they are guaranteed by the county or city governments, which I thought would be relatively safer than other bonds.
