I don't know, but they advertise it on their website. It is owned by Jeff Rann who also owns Rann Safari in Botswana. But frankly most of the exotics here are so expensive that unless your time is worth a lot more than mine it's cheaper to make the trip to Africa. Some examples are:
Wildebeest $5,500 vs $950
Zebra $5,000 vs $1,200
Impala $5,000 vs $350
Blesbok $5,500 vs $400
Sprinbok $5,000 vs $380
Kudu $15,000 vs $1,500
Ironically they are listing Sable for $15,000 also which is around $10,000 in South Africa.
Heck JJHack has a 9 day (7 days of hunting) package for $4800 (plus air fare).
