When?...or as kids in the car on long trips are wont to ask every five minutes, "Are we there yet? Are we there yet?"
I think no later than Sept 15th..
Dad straightened us out on that very early in life. "Yep, we're here. I'll pull over and we'll all get out, ok?" [puzzled looks] "Well then, I guess we all know that we're not there yet."
We'll all know when we're there, old sport. ;-)
