I love helping teach my mates to board and have done for many years now..
One big problem I've had is my bum getting wet when waiting for the learner who is walking up some hill as fell at the bottom of the bump ( we all remember doing that and still do sometimes)..
I was chatting to the guy in my local snowboarding shop and he said I should get knee pads and kneel instead of sitting on my bum..
So this year 2011 I'll be giving it a go and will let you know if it works out.
I don't wear any padding or helmets as I have a fear of going faster (to fast) if wearing safety padding and alike as my brain thinks I'll be unbreakable!
