I have to agree with bsmith and Leigh here, 19lbs. seems fine to me. In fact, I'd say it's a win-win situation because by carrying extra gear (within reason), you not only heighten the chances that you will be prepared if TSHTF, you also give yourself a better cardio-vascular workout in the process.

If I'm not carrying at least 20lbs. in my daypack, in goes the solar-powered, double-insulated, titanium coated espresso maker.
