How about garbage trucks? What's better than having two of them side by side in front of you so you've got nowhere to go? Watch as they peel out! Be in awe of their acceleration! See the diesel spew forth and bury you in soot! Marvel at their ability to hug the freeway interchanges (side by side of course) at an eyeball imploading 5 mph!

Ah well, that's what happens when you not only live near a quarry but also a land fill. Some people have all the luck.
