And do you need to reserve a spots or area of that person wants to throw a event at the park

Not sure but a great place to get hi!

Yes you should to cover yourself from any problems

Spots are first come first served. If it's a large group over 100 people then probably contact Sacramento Parks and Recreation Department. But for a birthday I wouldn't worry about it.

No reservatiin. Public park. But...1st come 1st serve. Just get there early and set up.

Ten years i know you had too pretty sure you do there is a lot of area have one

Yes
