Maybe I'm strange, but I can REALLY recall handling/throwing my first REAL hand grenade....VERY vividly. More so than many other of life's BIG moments. The feel of that cold metal in the hand. The heft. Pulling the pin. I found it to be quite memorable and exciting.
It would be fun to have a case or two to rid the back forty of gophers, or for the occasional bothersome skunk under the shed.
