One issue we noted was that the large rubber bands used to secure the tops of the pallet covers are snapping due to UV exposure. The bands that have broken will be replaced with twine and thus the twine vs. rubber bands experiment has been answered. For use outdoors, twine endures much better than the large rubber bands.
A big storm is approaching tomorrow and our next steps are to clear away any branches that have fallen on or near the bricks. We also plan to clear the weeds growing around the base of the pallets. This should ensure our bricks are protected for the remaining winter months. -JK
