DIRECTIONS FROM I-55
---------------------
* Take I-55 to I-90/94 West.
* Take I-90/94 West to the Irving Park Road exit.
* Make a Right (East) on Irving Park Road.
* About one mile from the highway is Elston. There is a light. It is a
  diagonal street.  
* Make a Hard Left onto Elston. The studio is 2 blocks or so on the West
  side of the street. If you come to another stoplight (just past a
  plant nursery) you've gone too far. Parking is available on the street.
