I got hung up on a technical climb coming out of Anrothar's Alley last year, fell/stepped off the bike, grabbed a tree (about 10-11" diameter) to keep myself from going ass-over-tea-kettle down the hill, and the TREE FELL DOWN!!! Fortunately, it didn't end up landing on me, but puckered they hell out of my (and the guy riding with me's) butt!!
I've had other close calls at Mahlon with high winds and branches flying around...so I avoid riding up there on windy days now. And I hate riding road when the winds are high and gusty...so...well...tater day for me!
