For many years I had access to a large walk in cooler and game processing place at one of the local ranchers. Those folk passed and now I have to find another option. A guy I know who raises and sells his own lamb and goat meat told me about a great option. You build your own small, say partition of a garage, hang a small, wall mounted AC unit and add a device called a "Coolbot". The Coolbot unit overrides the air conditioners controls and allows the unit to run down and hold 40 degrees which is the temp I like to hang deer. These units cost $330. I already have a small space in my garage because a Vet used to own the house and she set up the space as a lab. I just need to install insulation and buy a small AC unit. The site for the outfit that sells the coolbot units and has info on how to build a walk in cooler is: storeitcold.com There are also some youtube videos of folks building theirs using these handy units.
