KAYE: Pope Benedict XVI heads to Madrid tomorrow for world youth day. More than a million people are expected for the largest gathering of young people. But protestors are already lining up, many opposed to the estimated $72 million being spent to stage the visit. Al Goodman is live in Madrid where preparations are under way. Al, I understand there has already been an arrest.</s>AL GOODMAN, CNN CORRESPONDENT: That's right, Randi. There's a Mexican national, a 24-year-old man studying chemistry here in Madrid. He was detained on a charge of terrorism, potential terrorism. He was planning, authorities say, to attack with noxious gases a protest march this evening that was going against the visit of the Pope. He wasn't going after the Pope. He was going after protestors who were protesting the Pope's visit. And so he's now in custody and that march is going on at this time. Also, it turns out that he was a volunteer for the organizing committee for the Pope's visit. The committee told CNN he had gone through the volunteer procedure and he was arrested on Tuesday when he went to pick up his backpack and his green volunteer shirt by plain- clothed detectives. Randi?</s>KAYE: You mentioned the protestors. What about security there? How prepared are they to handle the protestors?</s>GOODMAN: Well, there are 10,000 police officers on duty. Some of what the protest has to say is that they fear the government money is being spent on this. The organizers say no, there's no money to the taxpayer, about 10,000 police officers. Spain has a lot of experience in organizing big events, the Olympics and international summits, so they think authorities say it's going to go off all right. At this hour, that protest against the Pope's visit is going, we're told peacefully. We were there a short while ago. Randi?</s>KAYE: All right, Al Goodman, thank you for the update. Well, from bees to lip balm -- what's the buzz about? We go in- depth with a couple of suburban farmers. Keep it here.
