A little off topics here but -
Do you mean to tell me that there are no borrowing pests in Perth - Oooh I am so wanting to visit Australia and this is just another plus in my book. Not that I would be troubled by borrowing pests on a visit, but this is just another good thing about Down Under. It seems every little pest we have borrows, roots around, eats roots and bulbs, and basically destroys every type of garden that is put in the ground in the Central U.S. (Ha)! Now they say we are possibly going to invaded by Armadillos (HUGE borrowing invaders) soon as they are moving their territory Northward. AAARRRGGGHHH.
with envy!!
Now, resume topic ----
Several suggestions for a floor covering here, but it sounds like plastic is a must no matter what you cover it with.
