Great idea with those rubber bands!
I've read that bungee cord will loose it's ability to retract when temperatures are very cold (anyone know what temp-range that is?).
So, I'm wondering if some Silicone rubber bands would be better than the standard ones for this use, during cold temps??

Nature's peace will flow into you as sunshine flows into trees.
The winds will blow their own freshness into you, and the storms their energy,
while cares will drop away from you like the leaves of Autumn."
