In the mid-70s, my college buddy Murph, and I bivied part way up the east ridge of the Grand Teton. It started raining that night and so we retreated the next day. My next encounter with the east ridge was in the mid-80s when Michael Franklin and I attempted a winter ascent. It snowed considerably during our bivy and we immediately went into retreat mode, thinking the east ridge snowfields might avalanche.
Over the years I have climbed the Exum Ridge many times - including the complete lower Exum - as well as the Petzoldt, Underhill, and North Ridge of the Grand. I will probably have to wait for my next reincarnation for another attempt on the East Ridge.
