Each side seems to host their own reunions. It is pretty hard to get everyone together at the same time, as you can imagine. Weddings and funerals are pretty well attended, but there is always somebody missing.
I had to laugh at your comment about reserving a National Park spot. Can you just imagine? LOL!! You would definitely need a lot of space. Think about how much food you would need, too. Ahhh, my head hurts!!! LOL.
I remember the last reunion I went to when I was 15. My great aunt and aunt and uncle shared a large lot, bordering on forest. It was full of tables, kids and grills. We had an old fashioned clambake. I would hope it was potluck ;-)
All I remember is that some of us cousins were going to swipe Aunt Agnes' homemade wine, but another cousin snitched on us, hahahahaha!
