It 's been tough getting good photos around here lately , even though the weather has been beautiful all week long . I decided that a sure bet was the Butterfly Garden at the Pacific Science Garden , so I asked Lael to go along with me for a day out . Unfortunately , after we drove all the way to Seattle and paid our $ 10 parking fee , I discovered that the Butterfly Garden was closed for the week . Needless to say , I was n't happy about that , but I was n't about to leave , either .
According to the above context, answer the following question.
Why might the Butterfly Garden be closed ?


They were doing maintenance and repairs
