GEP.... yes agree that assumptions make an ASS out of U & ME = possible dead pilots and broken aircraft....
Just to be clear... We used the Notam from the "official" site, SkyDemon simply gave us more information than "Brentwood" and a list of lat/long numbers - still had charts, plogs, Wx, Notams, everything else to provide as much data as possible pre-flight...
Interesting thought re the GPS... didn't use one yesterday tho' so didn't affect our navigation but it's a consideration for the future - thanks...
