I believe some localities do exhibit certain traits, or they are more prone to exist within a certain locality (black head caps, speckling, light ground color, etc.). However, it does appear you can find similar patterns/colors within all the locality based animals (ie, broad banded blairs phase, thin banded alternas, light/dark groundcolor). Locality also proves to a degree that an animal is pure and not a hybrid that was bred to accentuate desirable patterns or colors (which may have happened to thayeri kings). Some people like locality because it gives perspective to the actual geography and ecosystem the animals were captured/derived from, or the rarity of the species in that area. I love locality animals, but nice generics make me drool too!! At one point I was getting big into the locality thing, but realized I was keeping ugly, picky animals for not other reason then where their genes were from. It didn't really make sense to me, so I am not as gung ho about locality as I once was.
