KINGSPORT — Otto the river otter was a unique and wonderful animal that captured your imagination and your hearts. In the wake of his recent death, Bays Mountain Park officials say the response from visitors and the community at large has been encouraging and not at all surprising. Park Manager Rob Cole offered these frank comments to the Times News this week, speaking to the greater Tri-Cities region about their cherished 2-year-old river otter that died last week. Otto fell ill nearly two weeks ago after park officials found grapes in his enclosure on Memorial Day.
