This year was the good harvest of gourd, which urgently need to transport to storage. To transport the pumpkins will be used powerful tractor-trailer. But there is a problem, tractor trailer with high sides, but nothing is closed at the top and there is a strong likelihood that pumpkin on the road can just fly out of the trailer. Moreover, you have to go that way, where a huge number of high descents and ascents. So try to drive so carefully to transport all the harvest.
