I find summer competitions in any of the southeast-Asian countries problematic, to say the least. Even Atlanta was difficult in July 1996 and caused some serious health concerns for some horses. Perhaps it would be best not to send any equestrian team to such locations, unless there is adequate climatized, indoor competition space...
I'd like to hear what equestrian events are scheduled. I would also have some concerns about the health of the horses if a U.S. team is sent.
