The best treks are when you are either alone or with somebody. Yes. I like my solo time, but I also enjoy good company. I never worry about someone getting me in trouble. If I don't like it, I don't do it. Most of my hiking partners either taught me or I taught them so we come to an easy consensus.
More than once, after checking the weather, I have driven 250-300 miles, hiked 3 or 4 miles in and then smelled or felt a storm coming in. Nothing to do but turn around, hike back out and drive home again. I did that once in the Sawtooths a few years ago. I was just one mile from my planned campsite when I felt a change in the weather. I just said "dog, lets go back". And we did. By the time we got back to the car, 8 inches of partly cloudy had fallen. That storm brought the onset of winter and wasn't even forcast. Getting caught at 10,000 feet in those conditions could be ugly.
