There is also the classic laddering strategy, where you buy bonds with a range of maturities in order to reinvest the principle from shorter maturity bonds if you anticipate rising rates on longer maturity securities, while mitigating the risk that rates do not rise (i.e. inflation never comes).

There is only one safe money and that is whatever the fed is willing to prop up. There aren't too many things left though.
