You MUST Push the Button

by Chris MacDonald

push_buttonThis one is in Washington, DC. (That’s the Capitol in the background.)

Exactly what’s being demanded here seems to depend on how you parse the sentence. Is it “You must [push the call button and thereby call for walk signal] before daring to cross the street”, or is it merely “You must push the call button IF you want the walk signal”?

Thanks to Wayne for sending this.
