Wow, congrats on the show! This is going to be a great oppurtunity not only for you, but for reptile awareness in general! Maybe some people just end up flipping to the channel and will be educated about reptiles, and join the wonderful world of reptiles
I've got some ideas for you if you want them:
-You could teach people about field herping and what it consists of (Catch, release, photographs, optional documentation).
-You could interview some of the Ontario reptile breeders, that would always be cool
-Reptile of the week
-And don't forget turtles of course
Good luck with your program, Jenn! I hope everything goes smoothly
