Tracking throughout the NIGHT

Hi all my members.
Are you interested in tracking?
This is not the normal one, little bit crazy.

There are big 5 great mountains in the northern part of Seoul: Bularmsan, Sooracksan, Sapaesan, Dobongsan, and Bookhansan. They are called Bulsoosadobook.
We are going to track only the first 3 mountains not the 5.
This tracking starts at 9pm., estimated 12 hours.
If you want to join, please prepare own lantern, water, and extra clothing for cold.
