Luna loves the Gems and Minerals exhibit in the National Museum of Natural History. She loves going to the little shop and filling a bag of stones for $6. This is the second time we’ve done it, and she already has a pretty big collection of crystals and rocks. After we walked around the museum and looked at the different exhibits, we went to Union Market for lunch. We got some seriously delicious vegan Korean tacos from TaKorean and I had some of the best coffee in DC from Peregrine.
