Conservatory Closed Again

The embattled  Thunder Bay Botanical Conservatory is shut down once again because of falling glass.  The city says that late Friday  they discovered that a malfunction of a roof vent resulted in several glass panels to break. They say that caused shards of glass to fall into the safety netting inside the Tropical House viewing area.  The cause of the problem isn't known and no one is hurt.   The city expects the conservatory to open again next week.
