The Red Cross responded to the Valley Fire hours after it started around 1:20 p.m. on Sept. 12, Wilkes said.
There were as many as 1,000 people staying at the fairgrounds in Calistoga since it opened, most of them outdoors in tents and recreational vehicles. As many as 30 people were housed inside the Tubbs Building at the fairgrounds at 1435 N. Oak St., Wilkes said.
Wilkes said the Red Cross's focus there was on feeding and sheltering evacuees rather than collecting donations.
The Red Cross's preference for monetary donations enabled it to respond on the evening of the fire because those previous financial resources were already available, she said.
