I attended SW Night at the Padres, and got the Jedi Andy bobblehead - but I felt like the Padres didn't make a big deal out of this for the fans - while i saw a few guys in armor, i didn't see a big presence that indicated that the 501st/RL was present, and the Pads only had one bit of SW on the big screen (a video where a baseball fan and a Padres player competed to see who could name more SW characters in a minute). I heard other teams like the Angels really did a lot more to make it feel SW.
