We have all made decisions/choices that we would change if we could go back in time. The important thing is going forward, and correcting mistakes.
However, it is slightly annoying that every single time anyone makes a comment about ammo availability/scarcity that someone chimes in self righteously about how they should have stockpiled years in advance and that it is sooo easy to do.
I have a feeling that some posters, and this isn't directed at anyone in particular, have forgotten what is like to be young and broke.
By now, we all get the point, there is no need to endlessly lord it over everyone else about how shortsighted/unprepared/unwise some people were. It has in some cases come across more as bragging and self congratulating.
Just remember that not everyone is in the same situation as you, and sometimes, people have financial situations that didn't allow them to stockpile without undue hardship. And don't forget that young people, who are without a lifetime of experience, are allowed to make a few mistakes once in a while.
