We made our first trip to Florida when I had maybe 100 hrs. On vfr ff to ism, and was given a vector. A bit later she told me to resume direct to ism, which would've taken me right through the tfr. I was a nervous low time pilot, so I turned to avoid it. Suddenly I hear my tail number and "sir, I need you to go direct to ism. The tfr doesn't exist when you're talking to me. " in a very firm voice. I'll never forget that lol.Truth, every time I’ve been to ISM I get vectors right thru the TFR on the approach to 15.
