I've went Solo,Many Times,& I've also Rendevous'd Solo.I've also had Many close sightings of Predators,When going Solo!One person makes Alot Less Noise than 2 or more,& Animals in General,Have Less Fear,As Well! I 've Alway's tried to get Friend's to go Along,but when I'm ready to Go,I don't need to hear the Malarkey/Excuses/etc.,I'm Good to Go,& I'm Gone!I usually Avoid The Black Diamond trails that require Rigging/Rope,But I have used them on Occasion,to acheive my Destination!I'm Also Not, an Ultra-Lighter or Explorer when going Solo,It is Exhilerating for the Most part!
