I made a special catagory for bicycles because they are so prominently present in the streets of all dutch cities there is no getting around them, somtimes literally. Especially around bus- and trainstations there are such enormous herds of bicycles that it seems almost impossible to find your own vehicle back. Just imagine that you have had a few beers that have affected your memory a bit and you want to cycle home. Nightmares! I have seen people searching there crying of frustration.
