My work to locate government GIS server addresses has greatly expanded.
If you are looking for government GIS data anywhere in the USA then you might want to take a look at this list I curate as a public service. The list now has 1,400+ addresses for ArcGIS servers from the federal level down to the city level.
Worried about dead links? Got that covered with a weekly automated scan (my own code) of every server address. I expect there will be some tweaks to the list each week.
