yup, dwi back in the old days 70's was temporary, went away, not much 
happened to you. But today! here it is breath device in your car 1 year, 
$2000 fine, the revoke your drivers license and give you a limited one, 
another fine of 1000 at drivers license place, and it dosen't go away.

interesting 1880s book, did you need spcial glasses?  I have some 3D 
pictures, (two pix side by side) actually on glass, with a viewer has 
two lenses from paris about 1890 - 1900, tourist souvineers

think you are right, 'continue the research funding'  type of paper

your OK Mahipal, you add a different perspectives in this newsgroup, 
like adding in more color to the subject of things.
