We love river rafting and anything to do with boats.  Besides running rivers in the summer, Dave and Vicki Mackay started Mackay Marine Brine Shrimp Company in 1985.  The company operated during the winter months on the Great Salt Lake collecting Brine Shrimp Eggs, and it is now part of a Great Salt Lake CO-OP.   In the early days of Brine Shrimping, inflatable rafts were used, similar to the ones used on Grand Canyon rafting trips.  Over time, the Brine Shrimp industry moved to quicker Aluminum Boats with cabs to stay warm.
