Yeah. I did. I had to put it up in our colony…
My personal opinion – it’s a nice thing. Just the wrong day. One day earlier or later. Tisha Bav should be spent on just mourning the Bais Hamikdash a the sublime way of life that was lost. Ways of how to fix it could wait for another day.
If Rachmana Litzlan someone was killed in a car crash, the time and place to discuss traffic lights, signs laws etc. is not by the Avail’s house during a shiva call. There’s a time and place for everything.
I went along with it and put it up, the messages are important, very important, but it’s my personal feeling that it’s a bit misplaced. (again, my own opinion and feeling)
