Welcome to the very fun world of kings! I cxan tell you that you should enjoy your new snake.
Speckled kings are found in the western SE states such as AL, MS, LA, TX, and up the Mississippi River floodplain. They are Lampropeltis getula "holbrooki". The brooksi king is only found in FL and usually gets slightly longer and larger in build. It is Lampropeltis getula floridana "brooksi". Not sure how the current taxonomy holds, but different people use different terms. Some would like to see them split from FL kings while others want to lump them all together. Quite frankly it doesn't matter to me. Enjoy your snake! And post pics!
