Thanks for the info, roadwaydriver59, otherwise I probably wouldn't have heard about this BS one:
HB 5607 Allows US savings bonds to be declared abandoned after being unclaimed and unreedemed 5 years after final maturity and allows the treasurer to obtain a judicial determination that the bond has been reverted to the state.
So, if anyone is hanging on to their savings bonds, you'd better cash them in before you find out that they are not yours anymore.
