Ihave 4 questions. can someone with first hand knowledge answer this . ok soo guys so this isnt a homework

so my friends and i who are all 16, and 17 (there are 5 of us one almost going to be 18) we are planning a trip to the beach right after my friend's graduation.

1. we were thinking about going to huntington beach and want to have a bonfire but does anyone know if it is legal to have minors without adults using the fire pits?

2. what time would you recommend that we show up? we all are taking one car so we are car pooling but we want to make sure that we get a pit before they are all taken we plan to get their probably in the early afternoon but is that too late?

3. does huntington beach have a time of when everyone needs to go home? one girl out of our group is graduating and so its a congratulations party and we want to stay late. is that possible?

if you have any other things we should know tell me in the answer box and answer all questions. < 3 this is sooo appreciated you for your time in answering all of my long questions. but at least you get points ill mark brainliest for whoever was the most xoxo
