Hi David,
I'm in West Central Illinois and our growing conditions are very similar to those in Bloomington IN.
We lived in Bloomington for 3 years in the mid 1980's but unfortunately have lost touch with all our friends there. I was a postdoctoral fellow in the Biology Department and there were a couple of people there who were into orchids. Sorry I can't recall their names and they have probably moved on-- it was 25 years ago
Maybe if you ask around the Biology Department at IU you can find some fellow orchid enthusiasts.
Good luck
