... rest areas and road signs.

Whoever came up with rest areas is a genius. It's so great to jump off the freeway, take care of business, and fly right back on. They are great.

West Virginia has the best construction road signs. They are speed limit signs equipped with flashing yellow lights; they say "Road Work - Speed Limit 55 MPH - When Flashing." It's great because when they are not working, they turn the flashing lights off, and you can drive the regular posted speed limit. Like on Saturdays, you can drive pretty much through most of the construction zones at 70 MPH.
