Hello John,thanks for your kind and comprehensive critique,I hasten to add that I do know Gladys,we will have been married 50 years in 2012, so we are quite familiar with each others work,we are of course each others greatest guide and mentor,at least that`s what we tell our friends! Everybody has their own view which is as it should be.
At the moment I haven`t downloaded Google Earth,when I get around to it I`ll give it a go.
All the best
Les.
