A trip between a fish and a bird

The very last (this year's) trip.
It's after Christmas and the New Year is a few days away. But the body shouldn't be lazy for so long, so I decide to prove to him that reason and not stomach will be in charge. So I'm going on a walk Between a fish and a bird, i.e. between a Christmas carp and a New Year's duck or goose.
Before eight o'clock I get off the bus in Zbraslavské náměstí with the intention of going to Beroun. Honest thirty, we'll see.
