If you're planning to see Quad City Music Guild's Oklahoma!, I'd recommend getting to the theatre at least 10 minutes before the presentation begins. Those buying - or hoping to buy - tickets at the door should certainly arrive earlier than that; Friday's opening-night performance was already nearly sold out, and I imagine word-of-mouth will make the musical's second weekend equally jam-packed. But 10 minutes seems like an appropriate amount of time to take in this production's absolute beauty of a set, and besides, you might find yourself forgetting about the set once the cast shows up and gives you even more wonderful things to look at.
