I love this route, despite what Dow says :) Planters Valley is one of my favourite places to climb, including rock in the summer. You will most likely have it to yourself, and it is a loong way from civilization here. If the climbs in this area were twice as long, it would be world class - still enjoyable though.
Peter loves going up Planter's Valley, I am so-so on it. The route I believe I would enjoy the most is the last one (of the published routes) we have not done, Anorexia Nervosa. It has to be 10-20 degrees F colder up here vs most of the south Ghost routes. Really can funnel a cold wind. Weathering Heights was picked out bad by February. I suspect it is a bomber route in early January.
