Art enables us to find ourselves and lose ourselves at the same time. Apologies for the late post! I thought this was published, but apparently not. The film took a lot of preparation. They first had to go scout out the location with a guide. They then had together kits of food and medical care. It took them 4 to 8 hours each day to hike to where they were going. There was also a lot of equipment involved, which also had to be lugged up on this hike with them.
