*Seriously, I don't need to - there are enough idiot drivers causing tractors to take avoiding action and there are spuds all over the roads.
Death Tick
Death ticks are clockwork menaces resembling ticks, but about the size of a man’s hand. They are programmed to seek out a living target, jump onto that target, and siphon the victim’s life fluids. Once the enemy is a dry husk, the tick returns to its sender. Any tick failing to reach the sender in 10 hours releases a corrosive acid and destroys itself.
Prairie Tick
Prairie ticks are the scourge of the High Plains. These horrid bloodsuckers live in underground burrows and are controlled by a single, giant queen that rules over each nest.
