Walking around some shops in Sedona, I was surprised to come across a gift shop for Out Of Africa. The park itself is located in Camp Verde, 30 miles to the south. However, Camp Verde is small with very little tourist traffic while Sedona gets hordes of tourists. So this is probably a smart move to attract those tourists to their wildlife park.
In all my zoo travels there is only one other time where I have seen an off site zoo gift shop. The Nashville Zoo has (or had) a shop inside the Nashville Airport.
