Most of my finds have been solo and there are times when I have felt strange. But that was usually due to the location of a cache (urban, shopping center, muggleville). And those that are challenging hikes in the woods are strange sometimes as well but for different reasons like the possibility of injury or animal encounters. But that to me is what makes it exciting. Pushing myself to limits that I normally would not undertake. I've discovered some things about myself that I didn't know before. And in the end, if the strangeness I feel is due to the fact that I am worried about what other people may be thinking....then feeling odd or strange really isn't worth it.
