Is Ragtime playing ANYWHERE in the U.S. or Canada?  I can't find it
anywhere... why isn't it touring any more?

Good news! Although the Ahrens and Flaherty musical "Ragtime" isn't
being produced as often as it used to be, it is definitely still
around.

Some forthcoming productions:
  
FULTON OPERA HOUSE
LANCASTER, PA  US 
From 6/3/2004
Until 6/20/2004 
 
PARAMOUNT THEATRE, INC.
ABILENE, TX  US 
From 6/25/2004
Until 6/27/2004 
 
ROUND LAKE AREA PARK DISTRICT COMMUNITY THEATRE

This was the search string that gave me the best results:

Google Web Search: "ragtime" + "ahrens" + "flaherty" + "2004 OR 2005"
://www.google.com/search?hl=en&ie=UTF-8&q=ragtime+ahrens+flaherty+2004+OR+2005

I hope this helps!

Best,
Pink

Sorry about the delay- - great work!
