Any steam heat contractors near Bloomington IN?

Dielectricunion

I'm an electrician and not a heating guy, but I'm recently interested in learning about steam systems and exploring some of the old systems that are still up and running. I've been reading books and watching lectures etc. but, having no tangible steam system, I'm reading through a lot of things that I have absolutely no concept of. This is kind of a long shot since steam doesn't seem very prevalent out here.... but it would be cool to connect with someone who has experience here and might be doing service work on old steam. Are there many buildings left out here that still run steam heat?
