Campus Visits for Post-Docs?

An anonymous commenter (whose comment I can't find right now*) asks about what campus visits for post-docs are like. There were a couple of replies in that thread, but nothing like the sort of lively discussion for which we are known far and wide. So I thought I'd go ahead and post a real post about the question.

There are, of course, (at least) two different kinds of post doctoral fellowship: your teaching post-doc, and your research post-doc, and the two kinds are likely to have different kinds of campus visit. But I don't know about this, since I've never been invited to campus to interview for a post-doc.

What say you, Smokers?

*This was a little while ago, and it was posted in a thread that was mostly over. I meant to post a post about it at the time, but things got away from me. Then the person came back and asked to have a main post about it, and I meant to post about it then, but things got away from me again. Sorry. I hope this isn't too late to be helpful to that person.
