Fire extinguishers, smoke detectors ... etc.
I don't think I am throwing any though
One problem of accumulating stuff and making "kits" of different sizes is that sometime I FORGET that I have this or that. Sometimes I bought something and discovered I already had two ro three !! Sometimes I was lucky, just thinking of buying something when I found it in a drawer !!
Worst part is when you do need soemthing and you have already forgotten you have it , and you improvise or whatever .. and later you find out you do indeed have it.
I seem like a certified geezer, don't I ?? LOL
