Upcoming Family Reunion

Back in May I was informed of this years upcoming family reunion for my Dear Dad's side of the family. These reunions are sporadic, to say the least, and may happen for two years in a row and then not again for a few years. These reunions are also complicated because, though held in Ohio, are about a three hours drive from home for us .Anyway I just realized that this reunion is going to take place in less than two weeks. I missed the last reunion because my Mom was in critical condition and facing a second surgery on her carotid arteries. Thankfully this intricate surgery went well and Mom is the picture of health this year so I can't miss this reunion without people feeling that I am avoiding it. The problem is that Mike usually works on Saturday's so he will have to take the day off which I don't like to see ( The pay check really reflects a Saturday off)as well as me not knowing what to take. Traveling that far, it is tough to keep hot items hot and cold items cold. Of course there are coolers but I don't think that those reusable blue ice packs do a very good job and the ice melts and can make things soggy or if Tupperware lids come loose(trust me they all do ), can flood whatever is in the bowl turning it into a waterlogged mess.I have been told just to offer to bring chips,deserts, or pop or something like that but the problem is that I am not traveling the furthest. There are families from Georgia, some of whom just leave super early , come for the day and drive home after. Families that stay at a hotel the night before and after,There are families that live an hour further than I do, families of younger cousins who don't even have a working stove/ oven in their homes, etc.I am one of the few who cooks, so we have plenty of pop, chips, store bought deserts and other easy travel or pick up on the way things.I did make rigatoni with meatballs one year, added extra sauce and put it in an electric buffet roaster. Thanks to the power inverter I was able to plug it into the car's cigarette lighter on low and it was half decent when we got there. Of course Michael had to ride the whole way turned in the back seat making sure it didn't slide and spill in the cargo area on the way ( we tried to box it in but the roaster was warm so it couldn't be next to the cooler or anything that would catch fire) Another year I did pepperoni rolls but slightly warm they were not the hit I had hoped for.This year I am thinking of cooking a ham and taking buns for sandwiches. One uncle and aunt ( who live close by) always buy hot dogs and bring their grill with them so another sandwich is not really necessary but hey, if it works, why not. Maybe I will just keep my eyes open when I go grocery shopping and see what jumps out. Hey, maybe I will wrap a turkey in aluminum foil and put it on my engine to cook, like some travelers cookbook from the 1950's suggests, though I don't see this actually happening I will just have to keep thinking I guess.
