If you are going to be going through Edmonton any time in the next couple months, drop me a PM or e-mail and you would be more than welcome to come by and practice some probing. I found it was easy to learn when I knew what sex the snake was before I probed it, so I didn't have to worry about hurting them. It is very easy to do. Popping is also easy once you have done it a couple times - with any luck we may have some babies here that you can try on too. We are going to be moving though, so won't likely be around for the Red Deer or Edmonton fall show.
