During long road trips, you
may come across (or rather, they'll come across you) a lightning rod. It is basically a
car which has one goal on the highway... to keep in the triple digits MPH. You'll discover them most likely riding your tail if your in the left
lane.
The purpose of a lightning rod is to let them go. Chances are, you aren't obeying the speed limit either and, on a long road trip, you'll want to be pushing around 80.
Police fundraisers on the side of the highway will catch this guy first. Lightning rods will eventually leave the highway or disappear into the horizon, and ghost cars might
creep up on you.
