Snowboarding last winter (on about the only decent powder day of a shocking season):
Off piste in Sainte Foy, if you head way out left there's a nice line which eventually drops back to the resort. The bottom section is in the forest and is cut with lots of gullies, small drops, tangled thickets, etc. Very hard to ever go exactly the same way twice.
I was with a couple of newbies and showing off slightly. Dropped into one wee section, two drop-offs in a row, by this time going fast and somewhat off-balance. Alarmed to realise that I was in a small bowl with the only apparent way out being blocked by a fallen tree. Somehow managed to hop onto another fallen tree lying across that one, 50-50 it to the end, then land the (10ft+!) drop from the end of the tree. Cue round of applause from watching newbies.
Never, ever could I have pulled that off if I'd checked it out in advance and planned it!
