Of course, it's not one of those holidays when you receive innumerable gifts and gift cards, but it's just as important, or maybe more imortant than Christmas to some! This year, Memorial day lands on a Sunday, on May 31. The reason why it's so important, is because on that day, we celebrate and honor those who have served in the U.S Army.So let's take a moment to think about what they had done for us, and that they're part of the reason of why we exist. UoU Good Luck! (This tournament is placed on the day before Memorial Day, in case you need a special ceremony of any kind.)",
