My take on the challenge is probably quite different than most. I don't have to go to the beach to get my salt water fix (although, the ocean soothes my soul always). Our pool is a salt water system...and it is blissful. I have turned the heater on today for some much needed pool time with friends and family on the glorious 90+ degree desert weather this weekend. (And yes, the PebbleTec we have reflects the sky in just that amazing turquoise).
