Too funny about Zack yelling at the trucks! They are small but mighty! I think it is good for these little guys to get out and travel.Hannah, my birds love to go with us on vacation, I thought it might stress them out and they seem to have fun and get all excited, and Noel is actually a little nice to Zack on vacation. Zack even gets on the side of the cage and yells at the big truck going past us. So if you even see a P'let doing that on your travels, it might be us..
