I rarely can find anyone to go paddling where I want, as far away as I want, when I want.
If I confined myself to organized group trips, I would paddle the same things, mostly close by, over and over and over again.
I like to play things by ear, extemporize, change my mind and direction. For any reason or no reason.
So I mostly paddle alone.
I go solo when I have to but I would much rather have company. First, it shares the work...lol. Mostly though I want to be able to share the experience with another person. To bring to them the same joy that I get from being there. Who would not want to do that for someone you like.
