         I've been on the road almost a week, so my apologies for the 
late reply.

         I can answer this in two sentences --

         1.  I like using DGPS.
         2.  It gives me pleasure.

         I could expound on this a bit, but these two sentences 
pretty well boil it all down.  Actually, we could do away with either 
one and it would still say pretty much the same thing!  <G>
