What state or you in?
I have an uncle who is a horse trainer (racing), so I'm kind of familiar with the process, hence why I am curious about the state you're in. I may be able to point you in the correct direction.
Tx; I'm in Indiana. I have ordered a container, and have learned that I can buy the liquid nitrogen at a welding supply facility. So I think I'm all set.
Appreciate the reply!
