I need to plan an event during work lunch for co-workers?

Ever heard of pin the tail on the donkey? For your 4th of July theme, find a large-ish map of the US (from a bookstore) and a small flag with a thumb tack through it. Wherever your company is on the map, that is where they have to stick the pin there. They have to be blindfolded (with a sleep mask or something) and spun around three times. Then they hold their arm out and pin. They are not allowed to feel around the map. Use a marker to show who pinned where and whoever gets closest to the right spot wins a prize (maybe a little US flag decorative pin or something). Food, make it red, white and blue, like strawberries, blueberries and angel food cake. Well, that was the first idea off the top of my head! Good luck.
