Back in the 60's I was a member of the Polytechnic Presbyterian Church on East Rosedale. I was christen and baptized there. I don't know what happened to the congregation.
I remember as a child and young teenager riding the roller coaster. If I'm not mistaken it was called the Mad Mouse. Use to ride it at least 10 or 11 times when we went to the zoo. There was also a large merry go round.
