I've shot the Orlando match twice (2006, 2007) and is always very well attended (meaning more prizes now!) AND very well run. However they don't have the side matches you'll find at other matches (like Conyers, GA), but it's always a great time. It would be awesome if a Jacksonville match would come true!
Word is that the USPSA/IDPA/whatever handgun shooters within the former host club, Gateway, and who were the RO cadre for the GSSF match, were effectively ejected from Gateway by whatever other clique is actually in charge there.
It is unclear whether they have acquired access to another property or not, but if they do, and if it is suitable for a GSSF match, there is every chance that the Jax GSSF match would be reinstated there.
GSSF left budget open for it, in case it can be worked out.
