Mike Mullins recently made this statement in the Incidents forum:
=======================
Any person who is a USPA member must follow the BSRs at a Group Member DZ, at a non-Group Member DZ, in a farmers field, in someones back yard, does not matter where you are jumping. If you are a USPA member you are required to follow the BSR, period. As USPA members were involved in this jump they were definitely required to follow the BSRs. Someone who is not a USPA member, jumping at a non-Group Member DZ, needs only to comply with the FARs.
=======================
This is the first I have heard of this. I've jumped in a lot of places throughout the world, and while I use the BSR's as the default, there are cases where they don't seem applicable. One example is while I worked for a military freefall training program; the course instructor was not a USPA rated instructor (although he was certainly rated as such by the military.) Another example were water and demo jumps made in another country - they were made without "the advice of the appropriate USPA S&TA, Instructor Examiner, or Regional Director" (but again, with much advice from the local equivalent.) I've intentionally jumped through clouds while at a foreign DZ after the chief instructor briefed us on how to do it, and told us it was both legal and customary there.
Are all those things really considered no different than doing them at a USPA DZ?
