Visited in March. But, I might visit it again this June with my family while having our vacation at LA. I still need to figure out how to move my things across the country from Chicago and find a storage area for them near Caltech. I am an international student. So, I will no where to store my things once my apt lease here end in June. If anyone happens to know anythinng about that (aka temporary storage at Caltech), please share the information with me. =)
