Nice list!
In addition to your fine collection, here are a few others that I have:
Drifting Down the Delta, by E.S.G
Gypsy Days on the Delta, by E.S.G
Cruising the California Delta II, (re-make of "Delta" by Bob Walter's) (Hal's book is titled "Cruising California's Delta", which I have in hardcover as well as soft-cover)
The California Delta, by Carol Jensen w/Hal Schell's archives
Hal Schell's Guide to Cruising and Houseboating the Delta
Sunset Magazine's "Where to go Boating in California" 1973 (Hal wrote for Sunset for quite some time)
And of course, no collection would be complete without one of Hal's Delta Maps.
On top of that, I have every copy of the Bay & Delta Yachtsman going back to May 1976, which of course, featured Hal's monthly column, "Dawdling on the Delta". I have an enclosed room in the garage just for storing my "collectables". LOL
My wife knows how to keep me around. She's told me that if I ever even think of leaving her, she just might give me my guns, but she will be keeping my Delta collection of books and magazines!
I guess I'm hers for life!!! [:-love]
