You can find sand in a lot of places. I remember going into the water in LA in August and not being able to feel my toes after about 30 seconds. That water is cold, but I’ll have to admit that in the contiguous US So Cal has the mildest weather if that is what you are looking for. Did I mention the state tax rate of 10% for those making more then $52K and it goes up from there. Ouch.
