I saw that your girl got her first 2 Junior passes last weekend. Congrats!
Jennifer, I wanted to recommend The World of the Golden Retriever by Nona Bauer, if you don't have it. It's an amazing collection of photos of famous dogs prior to '93, most of them in color. The chapter on field trial Goldens is over 30 pages long with more field photos throughout including pictures of Goldens around the world. Nona contacted people actively competing in obedience, field, show, etc. and asked for pictures and information. It's a wonderful collection of pictures of dogs in our pedigrees of today.
You also might look for Julie Cairns' book on the Golden Retriever. She has pictures and stories about slightly more recent field trial Goldens like Duncan not included in Nona's book.
Hope to meet up with you at a trial someday. I am usually at the February trials in CA and occasionally at the Lost Hills trials when I am traveling through California. I hope to get to the GRCA National in Texas this year, so I may hit Lost Hills on my way south.
