Hi Porter, I took the AR in 2007. I have previously taken BCEP and ICS too. I think BCEP is a great intro to those who have absolutely no idea about mountaineering. It gives you a taste to come back more in ICS. ICS is a great course that teaches you more on mountaineering but gives you a little taste on rock. In AR, you get to learn more about rock climbing. It is not a class that will teach you how to climb 5.12 but concentrate more on rock skills such as gear placement and evaluation, rock rescue, aid skills, niffy tricks, etc. It is a very time taking class so if you plan to take it, you have to be committed for a lot of weekend to AR. If you do take the class you will get to meet some of the most skilled climbers in Portland and learn from them. Good luck in making the decision, have fun!
