As for why NITE keeps playing their games I don't have a definitive answer for you. We can all speculate as to why.
We all know BEHL is making the right moves and we keep growing a stronger base here in the mid to high .02's so we are getting much stronger imho. Just a matter of time now for the next leg up ;)
