13.11_Experiment of hill climbing(24/144times)

Today, I tried to do this experiment alone and at the night.

I couldn't see anything in the dark and it was so dangerous. 

I was only worried about the dog poop. What are the actual obstacles in the mountains?

I also found a glass-like material being thrown away on the way to the park. This reminded me of a frozen snowy road.

In addition,  I decided to personally record this experiment together in this way.

I also need to think about how to record videos in the future.

-What to record for what.
