I don't know if Trinity even bottles it. Maybe you could get a Denver or Colorado Springs BA to fill a growler for you. I'd go to the mountain board and see. I could possibly be persuaded to drive down there.
I just heard they were brewing up another batch, they usually bottle this one in 750's for about $18 https://twitter.com/#!/TRiNiTYBrewing/status/182962194042978305 Their batches are pretty small, brewery only and usually sell out before the next batch but depending on the beer they usually last at least a couple of week.
