Murray, what wonderful sites. This is the first time that I have taken the time to truly get into the information sites that you have been posting. I have kept the info on file. With the intention of SOMEDAY I will take the time. Now I feel like I have been cheating myself out of lots of good info. Thanks to all the effort you put into placing so many helpful sites at our fingertips. Hugs, Juanita CG for George 74 dx 98
