Once coast to coast U.S., 1965. TWO guitar cases, which was a hassle, but didn't hurt the frequency of getting rides from the musically curious. I remember one ride in particular from a navy chief meteorologist who was keen to play the twelve string, and we had a nice jam at a truck stop. On shorter north-south east coast trips I also put a toothbrush on an old suitcase handle which got a few rides from people with a quick eye and sense of humor. Only felt threatened once, and nought happened. Wouldn't recommend it these days. Probably just my increased caution.
