Was in the south, in the east - a little, then a long time, so I laugh delight about Baku Baku, Baku ... " I told a friend: "What, the train on the planet, You learned burly wind saw it, I saw it ...

Trips through the mountains are dangerous and exhausting
It takes ages to get to the Moon and back
Local citizens suffer from diseases, hunger,thirst, and wild animals
I prefer to travel by car
You should travel across the desrt to get to Deli 
Every 2 years he sails across the ocean
Airplanes make travelling much easier and safer
They are  rich and enjoy nice food while travelling
Engineersa lways look for a way how to get to the opposite side of the planet in hours
Work hard and enjoy luxury travel! :)
