Lost In the Crowd...NOT!

At the Day Without An Immigrant (and their supporters!) March, I saw plenty of old-school tactics (cardboard-and-markers signs, drums, flags, t-shirts), but also a LOT of cellphone use. Most common seemed to be this conversation:
Marcher One: Where did you go?
Marcher Two: Where did you go?
Marcher One: Well, I'm on Wilshire and Western now.
Marcher Two: What? How'd you get all the way up there? I'm still on Vermont!
Marcher One: Okay, I'll wait for you on the corner. Call me when you get closer.
So is it the same at Disneyland now? And in the grocery store? No more "we're all going to meet at the ____________ if anyone gets lost"? What a different world!
