The time between Saturday night and Sunday morning where all awesomeness seems to happen. It's after all the friday night and saturday day activities happen. It's after downtown happens and before you decide Sunday morning you want to curl up in a hole and sleep for the rest of the week. It's where all of your favorite pictures are taken and you have to ask your friends who the heck is that?
Last Sunderday was probably the best time of my life! I can't even remember how or why we did all that... but it sure was epic!
