Sonshine - I've just always gone by the humidity percentages, I don't know much about dew point other than something the weatherman tells us about. LOL. Actually I do know what it is, but never paid it much mind. Kind of like barometric pressure, but I know you can feel that change, especially when the weather change is sudden. I've lived in the city and now live in the countryside. When you're "at one" with the elements you tend to notice those changes more than in the hustle and bustle of the city.
Jeez, sorry to MoMoll for hijacking your thread to talk about weather. I'm done. I'm Looking forward to the new site too because I'm ready for a place I can fix posts or delete them! I'm a bit of a chatterbox anyway, pun intended.
