Global Street Art Kwest/Musical Pilgrimage: Plan Update #2

Wanted: Globe Trippers
So, I've recruited Emily and her friend Craig for this holiday next year. Em and I look like we are trippin' through Asia, Europe and the States. Craig for L.A only. Anyone else up for some international mischief?

Hit list so far in approximate order:

• Tokyo
• London
• Amsterdam
  
• Denmark
• Berlin
• Prague
• Vienna
• Venice
• Switzerland (singing in the hills)
  
• Barcelona
• Madrid
• Frankfurt (if necessary)
• Los Angeles
• Seattle
• Portland (for 4th of July!!)
• San Francisco
• San Diego (San Diego Comic Convention/start road trip)
  
• Grand Canyon
• Las Vegas
• Roswell (via Area 51)
  
• Kansas City (wearing red/ruby shoes)
  
• Memphis (Gracelands!)
• Nashville
• (East) St. Louis
• Chicago
• Detroit
• Cleveland
• Hershey (yes, home of the chocolate!)
• Arlington
• Washington D.C
  
• Philadelphia
• Conneticuit/New England
  
• New York City (end road trip/Final Destination!!)

I think that's about right - only discussed it through once though! Phew! Leaving round end of April - early May, returning Augustish -early septemberish?
It's their Summer! Yay!

Whaddya think? Any suggestions?
