My wife and I were talking about it the other day in fact. I wanted to get some rain gear for our son so we'd have it when we went camping and we can't seem to find it anywhere other than online retailers. We live in Central Florida. It rains here, Alot! Maybe not as much as Washington State but Alot more than most any place else in the States. I always had a rain coat when I was growing up, you could find them everywhere. Now, the only reason I can figure is that children aren't allowed to go out in the rain anymore. They might get wet, or cold, or something.
The best we could do for the moment locally was the cheap Ponchos you find at the hunting department at Walmart or the Sporting goods stores. Other than that, they sell alot of the Gortex, high end stuff. I just want a decent rubberized rain gear set to keep for just in case situations.
