There's an old computing proverb (emphasis on the old): Never underestimate the bandwidth of a hurtling station wagon full of 8-track tapes.
In the process of moving, I put all 600 or so of my CDs in my Subaru and took them to the other side of Boulder. Assuming an average length of 40 minutes (350 megabytes) and a 20-minute transit time (Foothills Parkway is the only part of the trip where I was really hurtling), the bandwidth was 1.4 gigabits per second, which is faster than most Ethernet. And my station wagon was only half full.
Of course, I spent about two hours putting the data into cardboard-protocol packets. And my back was sore after moving them all up stairs, through the house, and to the car. So maybe there's something to all this copper wire.
This is also the sixth time I have carried over three decades of National Geographic, a very dense publication, to a new location. Reading material relocation is my primary form of upper-body exercise.
 More about this move later. The destination is a wonderful house in northwest Boulder we're calling Lucky Gin.
