Re: “Pacific Science Center, at 60, charts a course for next 60 years” [Nov. 11, Entertainment]:

The 60th anniversary article about Pacific Science Center rekindled fond memories. Operating a nonprofit is always challenging, but the science center had some very positive impacts along the way.

In 1984 the exhibit “China: 7,000 Years of Discovery” was a communitywide event with more than 700 volunteers and a $1 million net for the science center. It is still the attendance record holder of all traveling exhibits at the center. There were also traveling exhibits developed by the science center that toured the U.S.

In the ’90s, there was an extensive outreach to rural communities with “Science Carnival” — a traveling interactive science center set up in tents — and a fleet of vans that went to schools statewide with interactive experiences. In 1998, the Boeing IMAX® Theater launched with “Everest.” Shortly after, the Tropical Butterfly House opened. Memory-makers included the Thanksgiving weekend Model Railroad Show, Bubble Festivals and awesome IMAX films.

Anniversaries are also a time to thank those who made a difference in the community. The era from 1980-2000 was a very important and special time in the history of the science center. Thanks to the community leaders, volunteers, members, donors, board members and staff who helped make a difference.
