working out

Driving to and from school I see about 3 or 4 houses that have exercise machines of various kinds on the front porch or in the front yard. 

Have you ever seen that? 

I often think, what would happen if someone random just started using the treadmill or lifting weights? 

What if I started using someone's outdoor equipment?

On another note. I've been working on this thing. It's caused much frustration. But alas, even without adult supervision, I think I might be able to figure out what is going on here.
