a once around the garage to see what he is doing

That chain looks like the one I had on my mini bike when I was a kid, I had a 12HP Wisconsin off of a cement mixer and a belt clutch off of a lawn tractor, What a ride! I was 12. Well maybe not that big but we scrounged what we could off of old construction equipment to build what we needed.
Yea the good old days.
I would spend the whole day at our town dump scrounging junk that I thought I could make something out of. It was right out the dirt road from our house. My own outside hardware store. Anything with bolts on it came home. Bicycles were like finding gold. If it wasn't for the dump I wouldn't have had a Bicycle. I built the coolest Chopper. I wanted a "Orange Crate" but My dad couldn't afford one. Yeah those were the days.
