Heading out for some time out, I once again have to drive to the nearest major airport and do a handover with a replacement pilot. The airplane is in for scheduled maintenance and will be at least a couple of days, so this time I'm dropping off the car and flying out this afternoon, and then my replacement will pick up the car and drive back to the worksite when he arrives.
The USA has great highways. They are usually well-paved, with yellow lines in the middle, clear lane markings and white lines along the edge so you don't drive off the road. They usually have lots of bright reflective cateyes while Canada typically has only the glue marks left behind after the snowplough scraped the cateyes off the pavement. Some amazing engineering goes into the urban highway ramps. Some places they are stacked five or six layers deep. I'm sure there are dozens of advanced textbooks and hundreds of engineering theses on how to curve and bank an exit ramp, how long to make an exit or entrance lane, and where to put signs such that drivers can interpret them in time to make lane changes.
There are national, state and possibly also county highways and they have different formats. So one sign might direct you to 131 North, 23 South and East Loop. And the signs can be on the same pole so you see "East Loop 131 North 23 South." And then you're looking for 23 North and you see "North 23" and you go for it, realizing as you're committed to the ramp that that's 131 North and 23 South. So you're going the wrong way. Fortunately it's usually simple to exit, cross under the highway and get back on going in the proper direction. Okay, further evidence that Aviatrix can't drive. What else is new.
Texas on ramps: Some of them live up to that state of the art engineering picture. And some of them appear to have been built by the Dukes of Hazzard as a one-off. I guess the highway goes through all kinds of towns, and all of them want access. I have literally missed highway entrances to I-20 because I thought the ramp concerned was one of those dirt roads that cops use to do U-turns rather than a legitimate highway entrance. After a time I came to realize that while the interstate has a dependable consistency from Shreveport to Fort Worth and on to California, the entrance ramps aren't necessarily paved. It lends the interstate an exotic flavour, like The Road in Zelazny's Roadmarks.
Oh, and an airplane cartoon, just so I don't have to put the non-aviation tag on this.
