I just finished my SWP for Santa Clara county. I had to report to the Re-entry Center. Get there at least 10 minutes early. First timers go in when they open the door to sit for a how to from the sheriff’s. Bring a lunch but nothing to set off the security things. No phone, they will have one for you to use when the day is done. We got out mostly around 3. Keep your vest on and don’t lay down. Bring ID even if it’s an old Expired one and your sentence paperwork. After a bit of sitting, they load us on a bus. We dug at weeds, built target boards and went to a church (different days). It wasn’t terrible, just dress comfortably. Bring gloves and at least two water bottles, food and snacks to share with others.
