All That Glitters exhibition
As a San Diego resident I take advantage of the Free Tuesdays at Balboa Park, where you can enter a museum for free. This week I went to the Natural History Museum where I got to see the permanent exhibit of animals from several periods, from dinosaurs all the way to modern whales. They also have art work in the form of painting and sculptures that are just amazing.
Right now they have a special exhibit called "All that Glitters" which is an amazing collection on crystals, gems, jewelry and has a lot of information about the San Diego mines, which I previously had no idea existed. Amazing museum for kids and adults.
The only drawback is the regular price can be high, especially if you are paying for several kids. So if you live in San Diego, do take advantage of the once a month Free Tuesday.
