  Corina: is it going to be very difficult
  Jeff: this track is quite heavy
  Jeff: so please, take good shoes
  Maria: sure, how long is the track?
  Jeff: about 20km
  Jeff: let me check it
  Maria: thanks
  Jeff: 21,3 km
  Maria: but it's only to the lighthouse?
  Jeff: yes
  Maria: so we have to take a bus back
  Jeff: I think so, to walk back would be too tiring
  Corina: and too boring
  Corina: doing the same way again
  Jeff: true
  Jeff: so I'll check the busses
  Ann: great
  Jeff: yes, there is one at 5PM
  Maria: just perfect!
  Jeff: :)
