The most fun I ever had at a party was at my sister's wedding reception (the day after her wedding). She had a pig roast and hawaiian shirts were the required uniform. It was an outdoor party with tents and picnic tables. Everyone was very at-ease had a great time. The party lasted from early afternoon until late in the evening. Looking back at the pictures brings back really great memories of that day and I know my sister will always remember her wedding reception with great fondness.
