Detroit area herps

I am near Detroit and I am looking for someone who is in the Detroit area to teach me how to sex ball pythons. I have seen the videos but I would feel more comfortable to show me if i am doing it right or wrong. So if someone is out there and willing to teach me I would be very grateful.

It requires a little practice but not too hard. I would swing by a show in your area since that will be convenient for them and most breeders will give you a little demo if you ask nice enough.
