You said you can freeze the leftover, which says to me that you (a) have the freezer space and (b) eat hot dogs and hamburger anyway. In that case, even though you have lots of other foods, I would buy plenty of both for everyone, so you definitely won't run out. It's a no-lose situation, just a little more cash on the front end, as you will eat the leftover later anyway. Have coolers and ice for the raw hamburger and mayo salads especially.

Consider bringing some bee traps if that is a problem in your area this time of year.

Congratulations! I hope you have great weather and a lovely day.

Thank you so much!
Actually... there is little freezer space. Her refridgerator is small with just a small freezer space but hopefully she can find someone with extra storage area.
Its been a difficult wedding to plan with me living up in BC Canada and her in Oregon and... we were given a months notice....... UGH!
I'm sure things will go off without too much of a hitch...and the day will be special.
thanks!

Also consider donating leftovers -- certainly salads, etc., that won't freeze -- to a local shelter. That's what we always do.

You could do real barbeque; smoke some pork butts for about 6 hours at 250 then shred, chop and freeze. Mix with barbeque sauce when ready to reheat in the oven. This is really good and pork butt is really cheap!

I've found for BBQ's you really need to look at age and gender and work it out that way.

Teenage boys need 2 burgers and 2 dogs, minimum
Teenage girls are tricky, some will eat 1 burger or 1-2 dogs or 1 of each, some will eat none.... you should have a veggie choice these days.
Women will normally eat one of either..usually a burger
Men will want two burgers or 1 burger and a dog.

Add it all up and then buy more of each..not a lot more.

These are just guidelines based on the people I feed.
