I'm about to start selling weather rock - just right for caravanning:-
They weight about 100Kg so it great for balasting the caravan to get the nose weight just right, When you get to the site you place it outside wher you can easily see it from inside.
It works like this. you look out of the caravan at the rock
If you can't see it, then its either night of foggy (or some one else has always wanted a weather rock and pinched it).
If you can only just see it, then its misty ( or the gorunds mans hasnt cut the grass for week)
if its dry then its not raining
if its wet its raining
if its bright - then its sunny
If its gently steaming - its been raiing but the sun is now out or the local hound has taken a fancy to it
If thers a white lump where you put, then its snowed.
If theres a yellow envelope stuck to it you know its annoyed a traffic warden
There is a deluxe vesion with a themometer attached, so you can then also tell how cold it is out side.
Guaranteed to be more accurate than the Met Office for local weather reports.
Any one want one? cost £3500 inv P&P - Uk sales only
