The Unknown Wife and I have made interstate moves five times in the last 17 years (our anniversary is in about a week and a half). Some moves have gone well, and some not so well. But at least we never used this guy.
As I recently read on another blog, TNSTAAFL (There's No Such Thing As A Free Lunch). On a related note, Unknown Wife has informed tme that if I don't get tenure, I better find a school to commute to, since she loves our current neighborhood). But I don't think it'll be too much of a problem - I have a pretty good publishing record so far, and I have 5 currently under review.
But just in case, remember - don't go with the big guy.
