Basecamp Climbing Gym recently issued the following announcement.
According to google/science: "We weigh less at noon and midnight because of the sun's gravity. These two changes in weight are less than one billionth your full weight due to the earth's gravity..."
And since we aren't open at midnight, you should probably come work on sending your project at noon because that means you have one billionth of a chance of doing a tad better, right?
