I received my student edition of ArcGIS 9.3 last week, got it all installed. I was hoping the new version would make some difference with my troublesome Foster quads. However, I had the same results when attempting to georeference. The Foster quads want to be 1/2 degree off, even when the map frame has the correct projection.
My hope of mosaicking the historic quads is over; now I have to figure out how to tell the story with the independent quads.
It's wonderful to have the software at home. I wish I had dual monitors like the lab because it's also handy to have ArcCatalog open in one monitor and ArcMap open in another.
