Throw a couple of tires on the driveway in front of the door. Once you
no longer need them, make a couple of tire swings. If you want to get
fancy, you could throw a couple more tires in the driveway and make a
race course for them.

I wouldn't put anything right on the door, as that would still transfer
the impact to the door, and they just aren't designed to take that kind
of use.

My kids (2.5 boys), ride their trikes down the driveway (a small, safe
incline) and use my shed to stop the ride. Eventually, they are going
to damage the wooden door.

Any thoughts about what I could use to prolong the life of the shed
door? I checked out the local HD, and didn't see anything that I
thought I could use as a safe bumper.

Anyone have any thoughts or suggestions on this?
