Miriam brings up a good point. However, in watching the garbage men I noticed how when they do pull garbage bags out of cans they sometimes fling the bags toward the open hopper on the back of the truck. The bags don’t always make it into the hopper, and break on the back lip of the hopper…causing food, glass, etc to fall to the ground. I think a combination of things may be in order…some to be practiced by the owners/renters in proper bagging of the garbage, and some more discipline pick-up practiced by the garbage men. Adam, the summer manager, can probably shed more light on things. However, I think it might be a good idea to bring the problem to the attention of the garbage company, and ask for their recommendations.
