We know of some countries where roadsigns, invariably warning signs for a children's crossing, can be donated. These signs are then captioned with the name of the donor (e.g. Austria, France, Madagascar, or the Philippines). In this system You donate your sign and that's it. You don't have to do anything else.

The Highway-adoption system is superior because continuous effort is expec­ted. After all, which company wishes an association with a less than perfectly clean road shoulder? Who would drink another piña colada if Island Fruit cannot control the litter on the stretch linked to its name? It is ironic, however, that it is the people throwing the rubbish who would blame the benefactor for the roadside not being spotlessly clean.

I almost overlooked the differences in the heap. Compare the upper half of both heaps: smooth curve top, straight line bottom. Notice also the second impro­bable cut-out bottom left of bottom heap.
