Thanks all for the invaluable information. DavidX - Great ! I'll e-mail you shortly. Samsonite - Human tower building ? I think I've seen a documentary that included some such feat - braves guys (and girls) - I'll take a helmet if I get that close ! Diana - Got the links, and very much appreciate them. MartindeMadrid - The Dali museum sounds interesting, and your web site is very fine - some beautiful paintings and I'll keep it in my favourites !

Thanks again - I only hope I can be such a mine of knowledge when I return ! Great website too Madridman !
