Is Electricity outlets that u can plug into to use a electric grill or radio?

There appears to be a couple outlets located out of the restroom facility that people can access. There might be a noise ordinance though if your music is too loud since there is a library and homes located by the park. Hope this helps.

Yes

I'm not sure, but if they do, it will be limited and you probably have to get permission from the parish to use them.
