I quote (because I really could not make this up)
"Explore Amsterdam by foot, tram, supply journeying or bike. Word of warning though with the bikes on a past calculate there are over 400,000 bikes in Amsterdam, if you are a taste wobbly it could be prizewinning to move in digit of the parks."
I think it is saying for the inexperienced, biking in Amsterdam can be daunting and it might be an idea to keep to the parks. However, I cannot be sure.
For the rest, well I challenge you to work it out for yourselves... particularly the paragraph about drugs and prostitution. Happy reading!
