Ice machines in Oklahoma homes are becoming more popular.  During my association with a Scotsman Distributor, I have learned that a lot of people have dedicated ice machines in their residence.
Nugget ice, such as found at Sonic Drive Ins, is very popular. A lot of single family residents prefer nugget ice enough to get a commercial machine.

Other home owners in the Oklahoma City area enjoy the under counter machines that produce the gourmet cubes.  Never the less, more and more people are integrating the commercial technology into their homes.
