If we wanted to have a birthday party at pioneer park is there a list or a sign up sheet or is it first come first serve basis?

I believe if you call the parks dept, you can reserve the shelter. The rest of the park is first come first serve.

I agree with Mike also, some key dates need to be reserved at the beginning of the season. Others you can reserve just a week or two in advance.

Mike is right. On weekends it gets pretty busy there, too. Lots of grad photos and wedding shoots.
