In reply to Lupine Lacuna:
I haven't done either climbing or jumping for a while due to a dodgy neck, but will as soon as possible with skydiving first choice.
I cannot imagine it ever getting boring, and I've not heard anyone else say so. The insanity of jumping out of a plane is enough to keep me keen, and as Tim says, there are always new things to learn and do. I have seen someone give up, but that was before getting out of the plane the first time.
And, particularly in England, there are plenty of weekends when it is too windy (>23mph) or cloudy, so if any doubt re the weather, climbing it is.
And yes Tim, all of my instructors too, most of whom base jump, said climbing is too dangerous and crazy.
