Granted the trees make it a bit more interesting - but you should have seen the size of the wave that left that boat there
Seriously we have a local strip with a pretty significant gradient - the reduction in ground roll is truly surprising. Since using it, my potential forced landing sites have tended to gravitate towards slopes as really short landing rolls are normal and that opens up a lot more places (in Scotland!).
But the first couple of times do get your full attention!
