When I learned the code, back in high school in the 60's, my "elmer"
made a great suggestion.

When you're out and about, when you see a street sign or a billboard,
translate that into code (preferably "in your head" so as not to attract
undue attention). This was highly effective for me; it helped to develop
both sending and listening skills. I still find myself doing this from
time to time, and I still enjoy working CW.
