Is near a Metra train from Racine to Deerfield or Buffalo Grove or close by?
Go down to Kenosha and you can catch the Union Pacific Line train going towards downtown Chicago. The closest stations to Deerfield and/or Buffalo Grove would probably be Highland Park or Ravinia. There is a train that runs directly to Buffalo, but you would own to ride downtown, walk out of the station and over to Union Station and detain the North Central Train. Here is the Metra website: http://www.metrarail.com where you can find where on earth you would want to go. Good luck!
