Nice work on these Uberben! I'm partial to #3 myself. They are all nice though. This is by far my favorite area to photograph. I've taken hundereds of photos in this and surrounding areas. Its a very historic area, tons of old relics and hideouts as you probably know. The ol' Mill District, tons of fun. My avatar is actually at the foot of the Mill City Ruins building, which have now been turned into some pretty nice lofts (that I'll never afford) Nice work on these. If you're ever out in this area again, feel free to send me a message.
