Wrist strap less than popular

This weekend we had to do some yard work, so I thought I'd try out the wrist strap (aka "leash") to see if I could keep Dylan close while we were working. Our yard is an obstacle course of dangerousness. There's the steep driveway paved in hard stones that Dylan likes to hurtle down at breakneck speed. There's the big drop-off over aforementioned driveway that Dylan runs toward fully intent on leaping into the oblivion. There are my neighbor's garden tools and large open bag of fertilizer lying around. There is the uneven yard with lots of tree roots and things to trip over and bang your head on. I literally can't leave Dylan alone for a millisecond, and his new thing is "escaping" the minute I put him down and running toward the area of most danger. Before he's even been put down, you can see the strategizing wheels turning in his mind and his eyes scanning for escape routes. So I thought with the wrist strap, I'd reward him for staying close and the punishment would be that he'd have to keep the wrist strap on if he didn't obey. I think he's too young to get the whole reward/punishment dynamic. He hated the wrist strap the second I put it on. Not as much yard work got done as we would have liked. Cristiano took this photo with his cell phone and said he'd keep it in case he ever needed to present it to Child Protective Services. Please.
