From Sea to Sea: An Exploration of Canada by Bicycle
British ColumbiaTrevor Hennessey
You can see in this picture the reason your apples in the grocery store are all beautiful and unblemished unlike the ones you grow on your trees at home. I asked my host what was being sprayed and he looked closely and said that it was just oil and not pesticides. I asked him how he could tell and he said the if the guy driving was in a full body suit with a respirator it was chemical but otherwise it was just oil. The sad thing is that right next door (and downwind) of this field is a retirement home.
