How I study during the vacation

I studied about American things during the summer vacation. First of all, American traffic is very different from Japanese. I knew that vehicles drive on the right in this country, but I didn't know people ride a motorcycle without a helmet. I was surprised at it. In Japan, it is a violation of traffic regulations. And I found that people can turn right when the light turned red. It was interesting for me. Second, I was surprised that the American flag is raised every where. I think it is interesting for Japanese people. Because in Japan, it is not a common scene. Lastly, I was very surprised at food. American food is very big, and the grocery store's shelves are very high. And in the supermarket, I found that people put the goods on the belt conveyor when they pay at the checkout counter. I think it is very useful.
