Mike, You can set which ever place you want as your "Home" or default location by long pressing location you want to set.
It allowed me to long press and set the city I wish AND shows a marker that it is the set city but when I look at the icon it still shows the city where I work on my home page as the default city.
I even went in and deleted that city, back to home page, and it was still there. Even funnier when I went back into "ADD NEW" the city I deleted was there again?
I think you can set the default city when you first set up the application. I seem to remember this option when I first set it up and I actually set it so that it only showed my "home" city. So put the widget in the trash and then add the widget again and see if you don't get that option.
