According to the dialogue, what will they do tomorrow?

W: Tom, have you heard the weather forecast?
M: Oh, no, I didn’t, but look at the sky, it’s beginning to get cloudy.
W: I hope it will not rain tomorrow, hope it will be a fine day!
M: Of course, we have chosen tomorrow as the date for our class picnic.
W: Yeah, we cannot have our picnic without good weather, sunshine is very necessary for eating and games as well as party on the beach.
M: Great! I will tell them!
W: Now let’s make some preparation for the picnic.
M: I don’t like to have picnic on the beach, I would rather to drive out in the countryside, en, how about the East Lake park? We can find a quiet place far away from the highway, and have a real traditional picnic lunch with chicken, potato salad and dill pickles and lemonade.
W: Well, I will prepare some cold drinks and beer. And how about some fruits?
M: Fruits are easy to go bad. And don’t forget to bring some plastic bags; we should not leave rubbish everywhere.
W: OK, when shall we meet tomorrow? What about 8 o’clock?
M: Oh, no, we will drive for at least 4 hours. How about one hour earlier?
W: No problem.
