Kirk: I googled it. Doesn't seem to be as much vs Hamburg, doesn't even have its own website. If you've attended a Hamburg show and will go to the Oaks show next Saturday please post a comparison. Also, if you are looking for rats, and are willing to drive to Hamburg, then go to the Hamburg site and have a look at the vendor list. There are a few that specialize ln rodents (you will be able to tell by their company names), and at least 1 of them is very near Hamburg so may allow you to visit their facility, especially with a purchase of ​>$30.
