Any Parks in BR that allows crawfish boil and grill?

Maybe Highland Rd? Each park has a manager and stuff, so give them a call

Most will allow burners for crawfish boils. Never tried a grill, but I can't really see a difference.

The problem is not allowing beer (officially). I've done it before and even had a "ranger" come by and let me know I wasn't supposed to have it there. He told me he wasn't going to do anything unless we caused problems OR if someone reported it.

We've done BBQ, Jambalaya, etc. never done a crawfish boil but have never run into any issues. My local park has a pavilion with limited electricity so we usually bring a generator.

Allowed as long as no alcohol. However, no one is checking what is in your solo cup as long as you are being responsible. A bunch of beer bottle or cans may get you in trouble with a ranger, but you may get a pass like someone said above. Pavilions are first come first serve and get used a lot during good weather.
