I'm not sure if HD has it or not, Susie. I usually go to Lowe's here.
But it is available at Amazon.com for those who might want it and not have access otherwise.
Your intense sun really causes things like the coir mats to break down more quickly, doesn't it? In CA, we always had car dashboard mats/covers or else it wasn't long before the dash was dried out and badly cracked (in spite of all the ArmorAll). Here, no one uses them, much less sells them. But that is a good idea about the coir ... at the end of the season, they always have liners and so forth on clearance. You've given me an idea.
