When Natalie and Gordon drive into the parking lot, it is a sunny and (almost) windless day as evidenced by the trees in the overhead shot. When he gets off his bike and she gets out of the car, the background trees show that there is significant wind.
Gordon pulls the curtain to Rosalie's room almost closed when he brings Natalie back to his trailer. In the next shot, the curtain is fully closed.
When Natalie first leaves her husband, she drives into a tunnel and emerges from on the west side of Manhattan. That is, she has driven east through the Lincoln Tunnel, presumably heading east. But immediately after, she stops at a phone booth to call her husband, saying she is in Pennsylvania, which is in the opposite direction. Had the intention to suggest a westward journey, she could have driven west through the tunnel to emerge in New Jersey.
