I am a regular at Sibson and drive some two and ahalf hours to get there which speaks for itself.
I find it to be the safest drop zone in the UK they check every canopy opens and pick up every off landing.
I also find there is vast array of experience in its members who are all generally willing to share this if asked.
It has a very happy air about the place.
Its manifest is fast moving and second to none.
If you find Sibson is unfriendly then the problem is proberbly you.
