and you know there has been controversy about the canal. in other words, transferring it to panama and so forth. my friend said, bob, i knew you would figure out a way not to give that canal to panama. you are taking it out one piece at a time. >> keeping it -- i mean, aside from being remarkably beautiful, it's significant. what is the impact really for both the u.s. and panama with the transfer? >> well, first of all, panama was well trained. they were ready to take over the canal. we had a law whether you liked the law or not, the treaty required us to transfer the canal. the challenge we had was to make sure it was in perfect condition when we transferred it. and so there were a lot of steps taken including the cut widening, new locomotives to pull the ships through the locks. hydraulic system to open up the gates for the locks. and so it worked. and panama has done really a pretty good job.
