All mountain ain't for me. Drops like that are starting to take longer for me to recover from. I like singletrack XC/trail mostly and I definitely limit my air time to as near zero as I can.
I like fairly technical ride that is challenging, fast as possible, but not requiring a pilots license. I consider this XC/Trail.
The people I see riding bikezilla, and dropping down the side of 2 screamers full speed to jump a log make my knees hurt just watching. I consider this all mountain/downhill/crazy as hell.
Don't get me wrong I'm not punk, I just want to walk well into my later years.
