Yes!!
Just look at yourself as in the position to get ANYTHING you want!
Look at BCI and BCC pictures and find the most attractive snake to you and you may want to wait, decide something might be worth the few extra weeks, and go big!
I'm not saying an expo might not have what you are looking for at all, it very well could.
Just saying if you have a "green light" to get a snake make it the one you'd pick over anything else.
Enjoy the show and I hope you score there!
