Finnegan's springpole was made from old bicycle inner tubes. You can see them to the right of the flag in this picture.
From top to bottom:
Flat webbing strap wrapped around tree
2 old bicycle inner tubes (free at bike shop... they were throwing them out)
Rope tug toy.
As you can see she really likes it. Just be prepared for the gawd-awful noises that your dog will make when playing with it.
