My parents are still around, but I'm in a similar situation. Once they're gone (a long time from now, one hopes), I'll be sitting on a pretty good nest egg. Without any kids, there's no one to which to leave it...so I'll be taking a lot of expensive vacations starting in a few years when I retire. Why leave it for the State to confiscate?
That's the plan, anyway.
God bless you son. I once thought I’d give it to United Way (now it would go to the Race Pimps), the Church (Catholics who educated me would give it to Brazil or Argentina or some other African shithole) or the Protestants who would espouse the queers. Nope, spend it.
