Casting a wide net is great, if you can afford it. I had 15 interviews around the country, and wound up staying locally, but interviewing around gave me a great perspective on different styles of program... it also let me meet a lot of big name people and future resident colleagues, so that part was fun.
One caveat I will have about recommendations - the information / impression you hear from people will often be semi-wrong or based on dated information... so try to keep a semi-open mind. At the same time, if you hear something from multiple sources, there's probably some truth to it.
Additionally, don't forget the growing database of residnecy interview reviews here. Pathology has one of the higher amounts of reviews, and I am in the process of slowly adding all mine. The 2008 applicants thread and rank/match threads might be useful too.
Finally, I want to throw in my recommendation for the program I'll be joining in July, Methodist in Houston... obviously I can give you a more inside perspective after July 1, but it has terrific faculty, great training, happy residents, excellent benefits, an incredible research track, and the cost of living cannot be beat! There are several programs in the area you could work into a single visit... and if you come down, I promise to buy you a beer.
