This is a good post, thanks for sharing. Coburg is a nice place to be, and your Grandpa is a very interesting man. It is not surprising that your Dad turned out so interesting too. That is a nice photo of the two of you.
I have been to Canada's Wonderland. It is amazingly fun, except for the wooden roller coaster called Wildebeast which is scary. DON'T go on that one alone. Maybe don't even bother.
I'm not sure how tall you are so I don't know which rides they will let you on. If they let you go on the huge waterslide do it! It is really a thrill.
