Charles River in early autumn. Boston would have become a somewhat boring city without the Charles River. I like a city with water, and the wide rivers give people breathing space in the city. During my short stay in New York, I was extremely impressed by the Hudson River, which was flying with seagulls, and the East River, which spanned the Brooklyn Bridge and the Williamsburg Bridge. So, despite the extremely expensive accommodation in Boston, I managed to find a Charles River homestay. The homestay is on Lighthouse Street, and several blocks in a row are red brick houses of the same style, old and elegant. Walking on the street at noon, I began to feel that the city was indeed proud of its long history. The next intersection of the hotel was facing the Harvard Bridge, and the Charles River appeared unexpectedly. The river was much wider than I thought it was, and the sparse urban buildings on both sides were insignificant. The water flashed and spread eastward to the port where the ship Constitution was moored, and down it should be an invisible entrance to the sea. The width of the Charles River reached its apex here. It takes about 20 minutes to walk from Lighthouse Street to the opposite MIT. It is a mile across the Charles River from the bridge, and it feels extra long in the strong sunlight, so cool winds blow on the river. Although it is still early, there are already runners passing by the bridge. So far, I think of it, Ren is in sight. I love this river deeply...
