1) Miscellaneous non-GPS tidbits> Natural Gas/Propane... New article from Joe
          Natural Gas/Propane Electric Generator AUTOMATIC startup sequencer> U-Build-it
    Here's a snippet:
        "I purchased a 8kw  WilCo/DYNA Tri-Fuel electric start generator last year to use as an
        emergency generator in my home.  I wanted a remote controlled start generator,  but the
        price tag of about $4200 was just too much greater than the $1900 Northern Hydraulics Co.
        charged for a standard electric start unit.  I figured with a little time and $100 or so I could
        come up with my own remote start capability.  Here is how I went about it and what I came
        up with...."
2) Information> Selective Availability... Updated by Jack

        I decided to retrace my drive on the day SA was turned off and record the current SA
        effect on the same identical topo map to get a more 'apples to apples' comparison...
        So, the lower topo map in the page below has been replaced with one made today with
        a G-III+ and active antenna... Also I've replaced the GM-100 base map plot with a
        City Streets map plot...
