County Park with street parking and no signs saying no overnight parking. Arrived at 8pm and stayed through the next morning, walking the dog in the park, filling water (one of the water fountains behind the bathrooms has a spigot perfect for filling a couple gallons of drinking water), and using the bathrooms (only open during the day). Also has a community center with pool + “showers” (the kind to rinse off after the pool) for a fee
