Having been a trucker, (hubby and I drove together as a team over the road) I can testify that there are lots of times that drivers get bored out of their minds! When you're waiting to load or unload you can't get out and go to nearby stores to browse or shop while you wait...you have to stay with your truck. If you have a valuable load, you can't drop your trailer and bobtail to find something to do either....
I crocheted a lot...knitted...read...I wasn't quilting at the time...shoulda! :)
