Good article.
I always find this perspective strange and fascinating, although far more common than I would have imagined.
I will start by telling you the fear/reluctance/anxiety around solo camping is very common.
As for me, the majority of my camping is done solo and as far from civilization as I can get given the time I have. Two of my most memorable campouts were actually solo bush camps in winter.
The first was a wonderful bush camp in the balmy november weather of the Chilliwack, BC mountains. Incredibly peaceful and stunningly beautiful.
The other was a magnificent bush camp in -15c weather in the mountains near Telkwa, BC, deep in the bush down decommissioned forest tracks. Both were wonderful experiences where I saw not another person save for one guy in a subaru driving by in the morning of the november camp. There have been many others, but these two stand out particularly.
For me, I deeply love the solitude. I'm very comfortable with my own thoughts, and I love to surround myself with silence and the works of God, to shut out the works of man for a time.
If you have any questions for someone with the polar opposite perspective, OP, let me know!
