I'm doing Mt Whitney East Buttres in June and Rainier (obviously a v different objective but shares some necessary skills with the Chogoria approach and the elevation of Mt Kenya) in a couple of weeks. Also Cathedral Peak in Tuolomne Meadows and planning to do more multi-pitch this summer. I only just started climbing a few months ago but am moving quickly ;)
I am currently living in Kenya and would be glad to meet up. Post pics of your summits. August will be a good time to summit Mount Kenya for the rains will have reduced. Its been raining hard this year.
