Peter, since you know the area...the Red Cross center for the San Bernardino fires is at the National Orange Show and it is still open. Kind of a small place to put all those folks in. (And Starbucks did not set up stands for us low life, unlike what they did in San Diego...) The insurance companies have moved out and are set up around here now, in the park and grocery store parking lots (Not bad views for the ones at Lake Gregory park)
Normally, they use Norton AFB, but it was so active with firefighting planes that it would have been too dangerous to have masses there. Usually those runways only see tumbleweeds taxiing...
Thank you for your servcie with the Red Cross. They have been, and continue to be, a tremendous help for everyone needing it.
