Thanks to all the feedback I think I've figured out some good things to bring to a barbecue starting with a crab salad. I'm not sure whether they'll be a lot of chicken or steak being cooked but this will be good. I can bring plenty of streamers and balloons but I'd have to get there early to help you set them up.
Alternatively, I might be able to bring a large smoker and you could do Texas barbecue which goes well with potato salad.
Or maybe you're planning to cater the event which wouldn't be a bad idea.
