We made lots of stops for pictures along the way. Finally got to Mount Vernon about 6:45 just in time for pizza and a movie about Hidalgo (horse movie) with the grandkids.
We tried and tried to put MM's address into the GPS unit but it would NOT accept that Mount Vernon was a city/town in Washington State. It even tried to tell me all of the states that did have such a town -- even one in Australia!
So I gave up and just left it on map view. Later when I was looking at a regular map I noticed that it was abbreviated as Mt Vernon. I tried that spelling -- the GPS liked it and all was well...
I'm not sure who's dumb -- me or the machine? Or should I blame the wise souls that programmed it?
