Steveanne is correct.
It is Oak Park, IL (basically the intersection of Lake Street and Oak Park Av)
JNA - as for signature buildings, look in the extreme bottom right-hand corner of the first pic and you can easily see Frank Lloyd Wright's Unity Temple.
Chet - That is actually the EL Green Line running through the right side of the first pic, the Blue Line runs alongside I-290 on the south end of Oak Park about a mile south of these pics.
Once our lease is up for our present apt., my wife and I are moving to Oak Park and actually intend on staying there for as long as possible. We even looked at a couple houses to buy, but the house market is a little too high for us right now.
