When you are local in a certain climbing area or about to become a local, it is not very frequent to climb onsight. I would either already know all the routes, or I would be making first ascents. Solitary Souls was one of those rare routes in Arco that I hadn't tried before. It was an apparent onsight challenge and a fantastic line on top of that! That is the reason why I was waiting for the right moment to give it a really good onsight try!
