After a long a grueling winter (ha!) spring has spring in every corner of the city. Butterflies are emerging, there’s science in the hills, bugs at the museum, a sea fair and boat tours along the coast, strawberries for miles and crayfish in streams. Once you’ve soaked up a little spring-y nature, you can head indoors to sit back and be entertained by a light princess, some heavy athletes and out of this world singers.
