Obviously, it's up to the will of the committee, but I want to add my input. I would echo my colleague's comments and would support taking it back to look at the facts and think about it before we vote on it. I'd also be more comfortable with an estimated budget before we vote on it.
I might add that if we as individuals take our commitment to the environment seriously, we may choose instead to minimize our carbon footprint and bring all these witnesses in by Skype or whatever, since it seems to me the point of this is that it be a learning tour. I just want to echo Richard's comments.
