Hello Bruce. We are on "tourist duty" as well visiting Joshua Tree & Palm Springs. I really like the soft light effect you achieved with the bison especially the first one.
I ended up using my FZ35 much more in JT than my LX5 because it had a much needed polarizer.
Interesting, I used to use the polarizer all the time when I did kodachrome film, but although I have one, I rarely use it anymore with the fz35.
