just want to reiterate: 2 years ago, you could just walk in, wait in a queue, show your ID, fill out a form, and walk out with as many birth certificate copies as you wanted. now, you get to wait several weeks for them to process the order. and this system is "new and improved!"
while it is probably new and improved for people who have already left oklahoma, since they don't have to come back, it really is massively crappy for people who do live here
