I'm not exactly sure what that net contraption is, but let's see if I can take a guess: it's meant for cyclists to toss their rubbish into as they cycle by. Basically a trashcan to be used by people in motion along the path? I hope that's correct, because if it is, that's just about the smartest and most novel idea I've seen in a long time.
David Hembrow has explained these blikvangers here:http://hembrow.blogspot.com/2009/02/rubbish-bins.htmlStrictly speaking a blikvanger is an eye-catcher, but as the word is composed of blik = tin or can, and vanger = catcher, the link is easily made.And the plural of crocus is crocuses in English and crocussen in Dutch, from Latin croci and Greek krokoi.
That's brilliant! What a great solution to a common problem.
Well, the most common thing to see in them are Heineken cans, so make your own decision on how smart that is.
