Train yourself to read Morse code, encrypted and not. Read the following morsels of encoded text. I use it to prepare for puzzle hunt games.
Some exercises use 'x' and 'o' to encode dots and dashes. You need to figure out which is dot and which is dash. Some exercises use '/' as a word break, and some do not.
Some encoded text may be lewd, derogatory, and/or copyrighted. I found it all on the internet so it's pretty sketchy.
