Well... That ended up being a bust lol. I had contacted a local feeder breeder on FB that had said he was going and he told me he'd bring a large selection to the show to look through. He did not have any dumbos, none of the varieties I was looking for either... There *could* have been some rexes in there (he had double rexes in a different tub) but the rats were not in the best condition and I am inexperienced with picking out rexes, so I didn't hazard it. Apparently no one brings live rats to the show except this guy (I guess fancy rats just aren't popular in my area) so I'll have to try other methods to get some quality rats.
