I did not want to give them any money so they became more aggresive and began holding my hand and said 'please, please' all the time. Finally I decided to give them some money but could not find the wallet.
The ride took us through mountainous areas, covered with dark green forest, with so many curves that I got sick. I wanted to vomit but I held myself back, as there were so many other next to me.
On the next day we took the tour to see the Peninsula. The tour itself was very boring and the guide had really not much to say that would interest me. The area was barren and completely flat.
