traveling trucking

ok I'll share that I'm a commercial driver. on my last trip I saw these signs. the sinclair sign=dinosaur are seen mostly west of the mississippi river. the woman behind the counter said that there is actually one in the state of new york. the last sign is found in walcott, ia. it's the world's largest truckstop. ive been there the truck parking lot is huge. and it has a movie theater, barbershop, etc. i do see many interesting things from the driver seat. but i can't just pull a big rig off to the side of the road for a picture everytime. sometimes not safe, sometimes not legal. sometimes don't have time to stop. hope you enjoy.
