I got to see the 501st Cloud City Garrison marching at the Starlight Parade here in Portland the other week, which was really cool! They were definitely a crowd favorite. I spotted a couple of Darth Vaders, a regular Leia, a slave Leia, a Luke Skywalker in flight suit, light sabers galore, and many, many stormtroopers. One of many Cloud City Starlight videos is right here (filmed by GERUNDITE).
