They rolled up their sleeves and gave some good will by the pint today near Goleta.
A blood drive was held in a special vehicle at the parking lot of the Santa Barbara County Sheriff's Department. Staff members and the public took part.
Everyone who gave a pint was treated to refreshments and a snack.
One of the donors was Valerie Walston from the Santa Barbara County Search and Rescue team. She is a regular donor, every three months.
"I have a very rare blood type," said Walston. "I am B-positive so I find it important to give blood as often as possible."
And with her smile, it appeared to be painless.
"You feel a quick pinch on your finger when they test your iron levels and you feel a quick pinch on your arm when they insert the needle. Otherwise no pressure at all," said Walston.
Donors were through the process in about 20 minutes.
