--- Night does not come!? ---
I took a walk at night of the day we arrived in Rochester, in U.S.
I took a walk in the NTID campus at night 7 o'clock. The sky is still bright just like daytime.
When I asked an American, he said that difference of latitude caused it to be late getting dark later during summer time.
In summer, it gets dark at 9 at night. With this time, it gets dark in the United States 2 hours later than in Japan and China.

When we visited classes at NTID/RIT, the student seemed not only to hear the teacher's talk,
but also to try to gasp the contents through experiments and making things.
