Well, since I LIVE two blocks from the Studio, I'll chime in here.

There are other sites and FLW homes further afield, but this is the core trip.

Take the Green line and get off at Oak Park Avenue. Go North on OPA and turn left onto Lake Street (West). In 2 blocks you'll see the Unity Temple on your left. As you walk along Lake Street you'll see our new overblown public library that we'll be paying for long after I'M dead. Also, take a quick glance at the post office, which is one of the better examples of depression era post offices that is relatively intact. After your stop at the temple, you can walk North on Kenilworth past the "big houses" to Chicago avenue - this is another 2 longish blocks, but no biggie. Be sure to stop to gawk and to wonder "who would want to live in something this big, how do they pay the heating bill??" Turn left onto Chicago Avenue and you'll see the Home and Studio on your left. After your tour of the studie continue down Chicago avenue one short block to see the three small FLW houses lined up together on the left side. Backtrack to Forest Avenue and continue south of the home and studio on Forest Avenue which is where all the FLW houses line up one after the other. None are open to the public except on tours a couple times per year. Continue down Forest back to Lake street and turn right. Stop at Starbucks for a well-deserved coffee, or there are several places to eat along this stretch of Lake Street. Like spices? There is a Penzy's spices on lake street - they're mainly mail order but for some reason Oak Park has a retail store. When you get to Harlem turn left and you'll see the El stop right there.

If you want to drive, there are several convenient parking garages, and during weekdays you'll have no trouble with on street parking in this area, weekends during tourist season can get dicey.

Total walking distance - about a mile?
