The choice A seems fiiting because it includes the Happy Trails Park in the sentence. It also indicates that it is a fond memory for Ben because it uses poistive words such as: familiar and brightly. My only concern since I haven't read the passage is that choice B sounds promising as well. Where exactly was his trailer? Was it parked in front of the Happy Trails Park? Because he 'sighed with satisfation' when he was about to exit the trailer.
