I must be a dumba$$ for not comprehending but I can get the same weather
info from DUATS that I can from flight seervice. The reason I always call
FSS for a briefing (even after I have used DUATS) is to go on record as
obtaining a weather breifing (for liability reasons???).

Now if I file IFR then FSS has to be used but why couldn't I file it on-line?
I'm not opposed to paying a fair fee for my use of DUATS (or the equivalent)
but then I should be able to file there too.
