Showers and laundry facility. I have included a link to their site. I talked to someone from there once when I got a free meal at a church and I looked into possibly doing breakfast or whatever there. They have mail service, serve meals, etc. I never went, but this seems to be the North County equivalent of Neil Good.

No showers but can be assigned a case manager to help with needs. I talked to another homeless person once. He indicated they helped him get clothes, new glasses and I think food resources. I never went.
