My wife is standing behind me while I'm watching the video. The first three comments were, You're not doing that. Then, I'm taking out another insurance policy on you! I think it would hurt to make a bike dance like that at my age.
I used to ride similar stuff on down hill mountain bike courses. The rock gardens, the log gardens, the lumber trails. Fun stuff with the right equipment. It's harder to turn off the gas when gravity is your gas though. Only had two related surgeries too!
