My First 4th July in the US

This summer I participated the great Boulder School. It was my first school in the US and I really enjoyed the experience. I eventually followed lectures of professors known just by reading articles and reviews. It was great!
Also from the “social” point of view it was very interesting to do some US university life. A special happening? Spending the 4th of July in the US and following some traditional celebration as the Ralphie’s celebration
