I would say that I am half and half. In the three seasons I will either go alone or with my wife, father-in law or my brother-in-law.

In the winter I am strictly solo mainly because I can never convince anyone to do anything but a day trip. Which is fine by me because winter is my favourite time to hit the backcountry.

I have tried to join local meet-up groups, but few of them seldom backpack for more than a weekend and for the most part, that doesn't interest me long term.
