Project...again

Okay. After hoping for a bit of input via my blog from some outsiders, I have received input via other means from outsiders. I am pretty set on the post-industrial cities idea and GIS. I am thinking of looking at a few cities in the US and a few in Europe. Maybe...Pittsburgh, Cleveland, Buffalo, K.C., Dortmund, Wales (yes, realize this is not a city), Manchester.... maybe looking at population variables, occupations, economic development activities, etc. Also, doing this on various time periods.
