Every fall, Churchill, Manitoba swells from a tiny town of 800 to one of 10,000--and all the new visitors are here to see 1,000 majestic, migrating polar bears. The business of being a bear guide is more difficult than ever, but veteran experts are determined to give the tourists the up-close experiences they want. This year, conservation officers are trying new tactics to help keep both the bears and people in town safe. Nobody knows what this year's bear season will bring.
