Where is the town of San Juan Capistrano?

M: So, Rebecca, what did you do for spring break7
F: I went to southern California. I was in Los Angeles and San Diego. Oh, and I stopped in San Juan Capistrano. That’s south of Los Angeles and north of San Diego. I happened to be there just about the time the swallows re-turned.
M: Oh, I’ve heard about that    they always return on the same day, don’t they?
F: That’s right, on March 19th. And they always fly away on the same day, October 23rd. In the meantime, they migrate over 7,000 miles to get to their winter homes.
M: Seven thousand miles    imagine! And always coming back on the same day!
F: Yes, except for one year, a long time ago    they were delayed for a day by a storm at sea.
M: So, what’s the town of San Juan Capistrano like?
F: Oh, it’s a pleasant little town. Once there was a famous mission church there.
M: Once? What happened to it?
F: It was destroyed by an earthquake almost two hundred years ago. But there is an old adobe church that sur-vived. The swallows build their nests in the walls and towers of that church.
M: You sure were lucky to be there on the one day of the year when the swallows return.
F: Well, I wasn’t there exactly on that day. I got to town a couple of days later——but I did see the parade celebrating the swallows’return.
M. They have a parade? The people there must really like those swallows.
F: Sure——they bring lots of tourists to town, and be-sides, the swallows eat insects——including mosqui-toes !
